a0864835a5 Bootstrap/Load: Remove the ability to alter the list of environment types in wp_get_environment_type().
The intention of `wp_get_environment_type()` is to provide a consistent means of identifying the environment type, not of identifying a specific environment.

Actual environments should fit within one of the existing types: `local`, `development`, `staging`, or `production`. That should cover the types that plugins and themes might be concerned about when toggling functionality.

6c76a13139 REST API: Fix multi-type schemas with integer fields.
In [48306] support for multi-typed schemas was improved to first detect the data type of the value before applying further validation. The `integer` data type was detected using the new `rest_is_integer` function. This function used logic, however, that assumed that the value had already passed an `is_numeric` check. This meant that if `integer` and `string` were both acceptable types, the value would always be considered an `integer` causing the later accurate type validation to fail.

This commit fixes the `rest_is_integer` logic to include an `is_numeric` check.

Props rtagliento.

153d07b93a REST API: In WP_REST_Block_Directory_Controller::get_items(), make sure the blocks data for a plugin is not empty before proceeding.
This avoids a PHP notice if the API returns a plugin with empty data for `blocks` key.

2e2ef9e538 Editor: Use wp_add_inline_script() instead of wp_localize_script() to pass the _wpMetaBoxUrl value to the wp-editor script.
This fixes a PHP 8 "Only the first byte will be assigned to the string offset" warning on Edit Post screen.

The correct usage of `wp_localize_script()` is to pass an array of data, not a string.

Fixes #51108.

0228dd6a5d Taxonomy: Allow for wp_count_terms( $args ) signature, making passing a taxonomy optional.
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.

Fixes #36399.

3b1d1bfa7a Code Modernization: Fix PHP 8 "ArgumentCountError: array_merge() does not accept unknown named parameters" fatal error in retrieve_widgets().
As per the documentation of `call_user_func_array()`, the `$param_arr` should be a (numerically) indexed array, not a string-keyed array.

As we can use the spread operator in PHP 5.6+, there isn't really any need to use `call_user_func_array()` anyhow, we can call the `array_merge()` function directly.

The caveat to this is that the spread operator only works on numerically indexed arrays, so we need to wrap the `$sidebars_widgets` variable in a call to `array_values()` when using the spread operator.

Using `array_values()` in the existing `call_user_func_array()` call would also have solved this, but the solution now proposed, has the added benefit of getting rid of the overhead of `call_user_func_array()`.

29bfc56ca2 Code Modernization: Fix PHP 8 "argument must be passed by reference, value given" error in WP_Comment_Query::get_comments().
The WP native `get_comment()` function expects the first argument `$comment` to be passed by reference.

The PHP `array_map()` function, however, passes by value, not by reference, resulting in an "arguments must be passed by reference, value given" error.

The PHP native `array_walk()` function does pass by reference. Using this prevents the error on PHP 8 and maintains the existing behaviour on PHP < 8.
