When a drop-in (such as `advanced-cache.php`) contains a PHP error, additional PHP errors are caused when displaying the error protection screen because `load_default_textdomain()` and `WP_Error` are not yet available.
Though recovery mode is not supported for `mu-plugins` and drop-ins, fatal error protection is. This change ensures the error screen is displayed when a fatal error is encountered within a drop-in and not a white screen.

This change removes redundant CSS properties for different health check statuses in favor of utilizing the `.dashicons` class already in Core to define them more consistently. This also fixes the vertical alignment issues.

- The About page now uses a CSS grid to layout its design, making the page’s structure more obvious and hopefully easier for contributors in the future.
- Removes some code that is no longer used (such as videos, mejs elements, etc.).
- Update images.
- Unnecessary HTML is removed from a string on the page. This was a regression.
- Only users with the correct capability should be instructed to check their site status.
- Fixes the placement of commas.

When recovery mode is triggered before the site’s locale has been initialized, the message displayed to the user and the email sent to the site administrator with the recovery mode link are always rendered in `en_US`. This change ensures the site’s locale is used even when an error happens early in the loading process.

When viewing Site Health for a multisite install, there are a few recommendations that are not appropriate and could have negative implications for other sites on the install if the administrator follows the advice provided.
For example, Site Health recommends that inactive plugins and themes for a site should be removed. On a single site install, this is a great recommendation. However, on a multisite install, inactive plugins and themes for one site should not be removed because they could be active for other sites on the network.
This change also disables the `test_wp_version_check_attached()` test for multisite. This test checks for the presence of the `wp_version_check()` function on the `wp_version_check` hook, which is not present for every site on multisite.

It's important for links to have enough information in them in order to be clearly actionable. Destination and purpose should be clear. For example, `debug` isn't nearly as useful as `learn how to debug issues`.

This fixes several bugs in the signature verification code:
Disables signature checks on certain incompatible PHP versions that cause math errors when opcache is enabled;
Prevents a spurious URL and subsequent error when downloading a zip file with query arguments;
Prevents errors triggered by third-party upgrade scripts as per #46615;
Disables signature tests for Plugins, Themes, and Translations, leaving only core updates.
At the 5.2 release the API servers will only provide signatures for core update packages, which is why messages are suppressed for plugins and other package types. Signatures for those other items will become available later.

WordPress 5.2 adds the `wp_body_open()` function, and the default themes make use of it. This patch adds a shim for `wp_body_open` to bundled themes so this function will also work in older versions of WordPress.
