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.
Additionally, pass the `$taxonomy` argument to `get_term_link()` to properly disambiguate the call.

This brings `wp_count_terms()` in line with other taxonomy functions such as `get_terms()` which technically no longer require a taxonomy. Similar to the previously modified functions, no deprecation warning is triggered when using the legacy signature.

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.

If sitemaps are disabled, previously there would be a rewrite rule for the sitemap endpoint. This endpoint would display the homepage since there was a rewrite rule. Now, Sitemaps are loaded, and the proper HTTP headers are returned.

If there are no pages and no static homepage, there will still be one sitemap including the homepage URL.
This change ensures that this sitemap is correctly listed in the sitemap index.

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.
This change also introduces a new `esc_xml()` function to escape strings for output in XML, as well as XML support to `wp_kses_normalize_entities()`.
