This affects:
* `validate_plugin_requirements()`
* `validate_theme_requirements()`
Historically, the `Requires PHP` header was introduced in #meta2952 for the Plugin Directory first, so at the time it made sense to have it defined in the same place as `Requires at least`, which only existed in `readme.txt`.
Since parsing of PHP and WordPress requirements was later added to WordPress core, the core should retrieve all the necessary data from the main plugin or theme file and not from `readme.txt`, which only contains the data meant for the Plugin or Theme Directory.
The recommended place for `Requires PHP` and `Requires at least` headers is as follows:
* The plugin's main PHP file
* The theme's `style.css` file
The place for the `Tested up to` header remains in `readme.txt` for the time being, as it's not used by WordPress core.

The test to confirm if Authorization headers can be used and recognized by WordPress needs to include a username and password combination that WordPress can compare against during the testing phase. The inclusion of credentials here would unfortunately also invalidate any existing basic auth session for the site, for example if the user had added this as an extra layer of security on their back-end.
This test is now skipped if the `wp_is_site_protected_by_basic_auth()` function detects that basic auth is being used, since the act of using basic auth to access the site confirms that this feature is working as expected in the first place.

This allows third-party plugins to avoid accidentally being overwritten with an update of a plugin of a similar name from the WordPress.org Plugin Directory.
Additionally, introduce the `update_plugins_{$hostname}` filter, which third-party plugins can use to offer updates for a given hostname.
If set, the `Update URI` header field should be a URI and have a unique hostname.
Some examples include:
* `https://wordpress.org/plugins/example-plugin/`
* `https://example.com/my-plugin/`
* `my-custom-plugin-name`
`Update URI: false` also works, and unless there is code handling the `false` hostname, the plugin will never get an update notification.
If the header is present, the WordPress.org API will currently only return updates for the plugin if it matches the following format:
* `https://wordpress.org/plugins/{$slug}/`
* `w.org/plugin/{$slug}`
If the header has any other value, the API will not return a result and will ignore the plugin for update purposes.

Allow developers to extend the Site Health screen with their own custom navigation tabs and pages.
This implements a new filter, `site_health_navigation_tabs`, which takes an associated array of tab identifiers/slugs, and tab labels, allowing developers to add their own subpage to the Site Health interface as new tabs.
To output a custom page, or add to an existing page, the `site_health_tab_content` action is triggered whenever the `tab` query argument is present and not empty. This action includes the current tab as its argument, which a developer would match against to only output content when relevant.
Props ramiy for initial patch.

Previously, when exporting personal data, if the JSON encoding of the data failed, the invalid JSON was still written to `export.json`. This change captures the JSON encoding failure and adds a notice to the UI.

After [48390], plugins and themes can be updated with an uploaded ZIP file. Strings were added for comparing the "current" and "uploaded" versions of a plugin or theme, but lacked context for each as to the object being referenced. This change adds a `plugin` or `theme` context to each of these strings for disambiguation.

On the "Reading Settings" page, the post excerpt was referred to as a "Summary". For consistency with the rest of Core, this change updates "summary" to "excerpt" both in the setting and the relevant help tab.
