When the XML sitemaps feature was originally introduced, the `lastmod` field was omitted because guidance at the time indicated it was less important for search engines, plus for some entities it was computationally expensive to add. Now that the guidance has slightly changed, we are revisiting this and adding `lastmod` where easily possible.
- Adds `lastmod` to all individual post objects (of any post type) in the sitemap
- Adds `lastmod` to the homepage sitemap entry if the homepage is set to display the latest posts.
No `lastmod` is added for the individual sitemap pages in the sitemap index, nor for term archives or user archives. Those enhancements require additional changes, such as storing the modified date for a taxonomy term when something is added to that term. They can be revisited in separate follow-up tickets.

When various methods parameters in child classes were renamed to `$item` to match the parent class for PHP 8 named parameter support, most of the methods restored the more descriptive, specific name at the beginning for better readability, with several exceptions for methods consisting only of a few lines.
To avoid confusion about why some methods do that and some don't, this commit aims to bring more consistency to the code, specifically in list tables' `::column_default()` methods.

While using reserved PHP keywords as parameter name labels is allowed, in the context of function calls using named parameters in PHP 8.0+, this will easily lead to confusion. To avoid that, it is recommended not to use reserved keywords as function parameter names.
This commit renames the `$public` parameter to `$is_public` in `WP_Sitemaps::add_robots()`.

Dynamic (non-explicitly declared) properties are deprecated as of PHP 8.2 and are expected to become a fatal error in PHP 9.0.
There are a number of ways to mitigate this:
* If it is an accidental typo for a declared property: fix the typo.
* For known properties: declare them on the class.
* For unknown properties: add the magic `__get()`, `__set()`, et al. methods to the class or let the class extend `stdClass` which has highly optimized versions of these magic methods built in.
* For unknown ''use'' of dynamic properties, the `#[AllowDynamicProperties]` attribute can be added to the class. The attribute will automatically be inherited by child classes.
Trac ticket #56034 is open to investigate and handle the third and fourth type of situations, however it has become clear this will need more time and will not be ready in time for WP 6.1.
To reduce “noise” in the meantime, both in the error logs of WP users moving onto PHP 8.2, in the test run logs of WP itself, in test runs of plugins and themes, as well as to prevent duplicate tickets from being opened for the same issue, this commit adds the `#[AllowDynamicProperties]` attribute to all “parent” classes in WP.
The logic used for this commit is as follows:
* If a class already has the attribute: no action needed.
* If a class does not `extend`: add the attribute.
* If a class does `extend`:
- If it extends `stdClass`: no action needed (as `stdClass` supports dynamic properties).
- If it extends a PHP native class: add the attribute.
- If it extends a class from one of WP's external dependencies: add the attribute.
* In all other cases: no action — the attribute should not be needed as child classes inherit from the parent.
Whether or not a class contains magic methods has not been taken into account, as a review of the currently existing magic methods has shown that those are generally not sturdy enough and often even set dynamic properties (which they should not). See the [https://www.youtube.com/watch?v=vDZWepDQQVE live stream from August 16, 2022] for more details.
This commit only affects classes in the `src` directory of WordPress core.
* Tests should not get this attribute, but should be fixed to not use dynamic properties instead. Patches for this are already being committed under ticket #56033.
* While a number bundled themes (2014, 2019, 2020, 2021) contain classes, they are not a part of this commit and may be updated separately.

Validate the requested sitemap is a string before attempting to use it in a provider. This prevents `WP_Sitemaps_Registry::get_provider()` from triggering a fatal error in more recent versions of PHP.
The errors can be triggered by items outside the site owner or developers control (such as a user visiting `?sitemap[foo]=bar`) so the code fails silently to avoid filling error logs with unfixable errors.

In each child class, renames the parameter to match the parent's method signature.
Why? PHP 8 introduces the ability to pass named arguments to function/method calls. This means the child and parent method signatures (i.e. parameter names) need to match.
Adds @since to clearly specify why the change happened.
Reassigns the generic parameter to the original parameter.
Why? Restoring the original name keeps the context intact within the method and makes the code more readable. An inline comment explains why this reassignment is made.
Note: Reassignment is done after the guard clause.
Why? To avoid unnecessary processing and memory should the method bail out.

The `WP_Sitemaps_Provider::get_sitemap_url()` method calls the PHP native `http_build_query()` function, the second parameter of which is the ''optional'' `$numeric_prefix` parameter which expects a `string`.
A parameter being optional, however, does not automatically make it nullable.
As of PHP 8.1, passing `null` to a non-nullable PHP native function will generate a deprecation notice.
In this case, this function call yielded a `http_build_query(): Passing null to parameter #2 ($numeric_prefix) of type string is deprecated` notice.
Changing the `null` to an empty string fixes this without a backward compatibility break.
This change is already covered by tests as 14 of the existing tests failed on these function calls when running the tests on PHP 8.1.

This avoids a PHP warning during sitemap generation if `get_term_link()` returns an error, e.g. due to term ID being shared between multiple taxonomies.

The previous filter failed the goal of allowing developers to filter all providers before they are registered, since it only filtered the built-in ones.
The more specific `wp_sitemaps_add_provider` filter enables exactly that, as it filters every sitemap provider right before it is added to the sitemaps registry.

While web crawlers are able to discover pages from links within the site and from other sites, XML sitemaps supplement this approach by allowing crawlers to quickly and comprehensively identify all URLs included in the sitemap and learn other signals about those URLs using the associated metadata.

This feature exposes the sitemap index via `/wp-sitemap.xml` and exposes a variety of new filters and hooks for developers to modify the behavior. Users can disable sitemaps completely by turning off search engine visibility in WordPress admin.
