Sometimes errors only occur in unusual code paths such as the maintenance mode or installation screens. Due to lack of tests for these scenarios in core, such errors are usually only noticed very late. This change adds new end-to-end (e2e) tests to prevent regressions in the following areas:
- Maintenance mode (presence of a `.maintenance` file)
- Fatal error handler (simulated with an mu-plugin that causes an error)
- Installation screen (verifying full installation flow & that there are no database errors)
Thanks to these tests, an issue was already found and addressed in the default `wp_die` handler, as `wp_robots_noindex_embeds` and `wp_robots_noindex_search` used to cause PHP warnings due to `$wp_query` not existing.
In the future, these tests can be extended to also test scenarios like localized error pages via `wp_load_translations_early()`.

In [5983], a call to `clean_term_cache()` was removed from `wp_set_object_terms()`. Since then, the `$term_ids` array that had been populated inside one of the `foreach` loops before being passed to the removed `clean_term_cache()` call has not been used.
This change removes the unused `$term_ids` variable.

When saving options from the Settings page, include the `'ping_sites'` option in the allowed "writing" options list only when the `'blog_public'` option is `'1'`.
Fixes a PHP 8.1 and above "null to non-nullable" deprecation notice in `sanitize_option()` ([https://core.trac.wordpress.org/browser/trunk/src/wp-includes/formatting.php?annotate=blame#L4952 which happens when here] as part of [22255]):
{{{
Deprecated: explode(): Passing null to parameter #2 ($string) of type string is deprecated in .../wp-includes/formatting.php
}}}
**Explanation**
[https://developer.wordpress.org/apis/options/#writing Per the documentation], the `ping_sites` option requires the `'blog_public'` option to have a value of `'1'` and must be a `string` data type. `null` is not valid for this option.
The relationship between the 2 options shows itself in the `options-writing.php` code ([https://core.trac.wordpress.org/browser/tags/6.5.4/src/wp-admin/options-writing.php#L233 shown here] and in [4326]), as the `textarea#ping_sites` only renders when `'1' === get_option( 'blog_public' )`.
**What happens if `'blog_public'` is not `'1'`?**
The `'ping_sites'` option will not be a field on the page. Upon saving:
* HTTP POST (`$_POST`) does not include `'ping_sites'`.
* Before this commit:
* The [https://core.trac.wordpress.org/browser/trunk/src/wp-admin/options.php#L333 option's value was set to] `null` before being passed to `update_option()`.
* `update_option()` invokes `sanitize_option()`.
* A `null` value for the `'ping_sites'` case was passed to `explode()`, which threw a deprecation notice on PHP 8.1 and above.
* With this commit, the `'ping_sites'` option is no longer included in the allow list and thus will not be passed to `update_options()` > `sanitize_option()` > `explode()`.

In [58418] a test was added without the `test_` prefix in its function
name, and because of that, it wasn't run in the test suite.
The prefix has been added to ensure that it runs.
In the original patch, due to a logical bug, a recursive loop to
transform the inside contents of the bogus comments was never run
more than once. This has been fixed.
This patch also includes one more case where `kses` wasn't
properly detecting the bogus comment state, and adds a test case
to cover this. It limits itself to some but not all constructions
of invalid markup declaration so that it doesn't conflict with
existing behaviors around those and other kinds of invalid comments.

When `wp_kses_split` processes a document it attempts to leave HTML comments
alone. It makes minor adjustments, but leaves the comments in the document in
its output. Unfortunately it only recognizes one kind of HTML comment and
rejects many others.
This patch makes a minor adjustment to the algorithm in `wp_kses_split` to
recognize and preserve an additional kind of HTML comment: closing tags with
an invalid tag name, e.g. `</%dolly>`.
These invalid closing tags must be interpreted as comments by a browser.
This bug fix aligns the implementation of `wp_kses_split()` more closely
with its stated goal of leaving HTML comments as comments.
It doesn't attempt to fully fix the mis-parsed comments, but it does propose a
minor fix that hopefully won't break any existing code or projects.

Previously `remove_pdf_alpha_channel()` used `Imagick::getVersion()` to validate the environment is capable of handling alpha. This was the incorrect function to use to check the module version as it will only provide the ImageMagick API version. This patch adjusts to instead use `phpversion()` as this is the correct method to get the Imagick version needed to determine alpha compatibility. This fixes a number of host tests that have been correctly failing on subsets of environments. Serendipidously, sometimes the API version was high enough to avoid shining light on this problem.

Replaces `trigger_error()` with `wp_trigger_error()`.
The usage of `wp_trigger_error()` avoids generating `E_USER` family errors unless `WP_DEBUG` is on. In doing so, users should not see these messages in normal production.
Notes:
* Removes `E_USER_NOTICE` when passed as an argumnent, as it's the default error level.
* An empty string is passed for the function name when its name is already in the error message or does not add value to the error message.
* Externally maintained libraries are not included.

[57545] introduced `wp_get_plugin_action_button()`. This function is documented to return a `string`. However, if the user does not have the appropriate capabilities, it returned `void`, which is unexpected.
Resolves the issue by moving the `return $button` to the bottom of the function to ensure it always returns a `string` type. On success, the button's HTML string is returned; else, an empty string is returned.
