audrasjb 12fc2d9146 Administration: Remove self-reference ("we") in WordPress Admin.
This changes updates many strings to remove self-references to an undefined "we" collective across the WordPress Administration.

The goal of this change is to better match the guidelines and recommendations set forth in the make/core handbook, specifically:

> the word "we" should be avoided (…) unless its made very clear which group is speaking.

Sergey Biryukov ab263f93e5 Upgrade/Install: Check if the `disk_free_space()` function exists before calling it.
In PHP 8+, `@` no longer suppresses fatal errors:
> The `@` operator will no longer silence fatal errors (`E_ERROR`, `E_CORE_ERROR`, `E_COMPILE_ERROR`, `E_USER_ERROR`, `E_RECOVERABLE_ERROR`, `E_PARSE`).

Reference: [https://www.php.net/manual/en/migration80.incompatible.php PHP 8: Backward Incompatible Changes].

`disk_free_space()` may be disabled by hosts, which will throw a fatal error on a call to undefined function.

This change prevents the fatal error, and falls back to `false` when `disk_free_space()` is unavailable.

hellofromTonya d4b3deddda Upgrade/Install: Remove 5.8 function and fix deactivate Gutenberg plugin version compare < 11.9.
Follow-up to [52165] where the `version_compare()` fails for 11.8.x versions. This commit changes the version comparison to < 11.9 for deactivating the Gutenberg plugin. 

The `_upgrade_580_force_deactivate_incompatible_plugins()` function is no longer needed in 5.9. It's redundant and unnecessary as `_upgrade_590_force_deactivate_incompatible_plugins()` deactivates those versions as well.

Removing `_upgrade_580_force_deactivate_incompatible_plugins()` and moving the deactivation logic back into the `_deactivate_gutenberg_when_incompatible_with_wp()`, thus removing the new private function `_deactivate_gutenberg_when_incompatible_with_wp()` introduced in [52165].

hellofromTonya 1f608d5d5c Upgrade/Install: Deactivate the Gutenberg plugin if its version is 11.8 or lower.
Avoid a fatal error due to `WP_Theme_JSON_Schema` and potentially other classes and/or functions redeclarations when updating to WordPress 5.9 with an incompatible version of the Gutenberg plugin.

This commit uses the same strategy from 5.8. Moves the plugin deactivation code (introduced in [51266]) to a private function for reuse in 5.8, 5.9, and future major releases.

Mike Schroder dd11076dc7 Upgrade/Install: Invalidate OPcache for PHP files during updates.
When files are copied into place, check whether opcode invalidation is available and attempt to invalidate to avoid unintended behavior or fatal errors from themes, plugins, or core.

Introduces `wp_opcache_invalidate()` to allow safe invalidation of PHP files from opcode cache, and a filter, `wp_opcache_invalidate_file` to override the behavior.

Replaces the existing calls to `opcache_invalidate()` in the plugin and theme editors to use the new function.

desrosj 1d6bd71ce4 Upgrade/Install: Use a unique error code when an update fails due to the PHP JSON extension missing.
This allows update failures caused when the native PHP JSON extension is missing to be distinguished from updates that fail because the site does not meet the minimum PHP requirements.

desrosj c6d3987b08 Upgrade/Install: Detect the presence of the native PHP JSON extension before updating.
The PHP native JSON extension has been bundled and compiled with PHP by default since version 5.2.0. Because the minimum version of PHP required by WordPress is now 5.6.20 (see #46594 and [45058]), the related polyfills and workarounds have been removed (see [46205-46206,46208]).

However, even though the JSON extension is now included in PHP by default, it is still possible to disable the extension in a custom configuration. This change will prevent sites from upgrading if the JSON extension is disabled to prevent compatibility issues.

Sergey Biryukov f19ecd19de Filesystem API: Use strict type check in the `in_array()` call for the `$skip_list` parameter in `copy_dir()` and `_copy_dir()`.
This ensures that parent folders with a numeric name are not accidentally skipped when only a subfolder is intended to be skipped.

We've extracted wp-includes/wp-a11y.js to a reusable package wordpress/a11y which is published on NPM. Let's make sure this package is also used in WordPress core. Once all the JavaScript is built using webpack, we can also import this package wherever it is used and configure webpack to load is an external.
