In [49084] (for #50679), wp_get_attachment_metadata() was changed to improve performance, but it had the side effect of eliminating the ability to call it with no arguments and have it default to using the global $post.
This change restores that ability, while keeping the performance improvements from the original change.
This changeset brings [50039] to the 5.6 branch.
Fixes#52196.

When App Passwords was introduced, the `wp_authorize_application_password_form` and `wp_application_passwords_approve_app_request_success` hooks were mistakenly duplicated and incorrectly documented. This commit corrects the hook names and ensures the correct parameters are passed.

In [49154] the async Site Health tests were changed to use the REST API instead of admin-ajax. An unintended side effect of this change was that the loopback tests which tried to ping the site's `admin_url()` were no longer authenticated because admin-cookies aren't provided to the REST API.
This commit adjusts the loopback test to use the front-end `site_url` which checks that cron will function properly. A follow-up ticket will focus on tests that will cover the file editor checks.
Props Clorith.

In [49162], GitHub Action workflow configuration files were introduced to run all of Core’s automated testing with the intent to fully transition after some time was allowed for testing.
After two full months of testing, the time to finish this transition has come.
We thank TravisCI for testing the codebase through nearly 20 major and many more minor releases.

The `twenty-twenty-one-ie11-polyfills` script now has a `null` source, and the new `twenty-twenty-one-ie11-polyfills-asset` (which points to the actual `polyfills.js` source) will be loaded only if IE is detected by through the use of `wp_get_script_polyfill()`.
Because the original script name remains the same, this change is backwards compatible with any code registering `twenty-twenty-one-id11-polyfills` as a script dependency.

While `loading=“eager”` is a supported alternative to omitting the attribute entirely, browsers follow the value of this attribute explicitly when specified.
Specifying `eager` would prevent the user from receiving any additional potential benefits implemented at the browser level, such as further mechanisms to automatically decide which elements to lazy-load.

Previously, `1.0.0` was used for the version. This is inconsistent with the versioning used in the other default themes, which use use X.X and not X.X.X.
This change corrects all `1.0.0` occurrences to `1.0`, and adds the additional context of `Twenty Twenty-One` to avoid confusion with `WordPress 1.0`.

Twenty Twenty-One uses PostCSS to convert the custom properties for Internet Explorer. Without a config file, the postcss command does nothing, causing issues in IE. This brings back the config from GitHub, which replaces all custom properties with the default values.

Appveyor was added to Core in [44594] to ensure that NPM and the WordPress build tools continue to work correctly on Windows systems as changes are made. Using an additional service for this was required at the time, TravisCI did not support testing on Windows.
[49162] introduced a GitHub Action workflow that performed the same testing. Since all automated testing is moving to GitHub Actions, using Appveyor is no longer necessary, and it’s preferable to have all automated testing in one location as much as possible.

When SimplePie parses HTTP headers, it combines multiple values for the same header into a comma-separated string. `WP_SimplePie_File` overrides the parsing, but was leaving them as an array instead.
That lead to a fatal error in PHP 8, because other parts of the codebase ended up passing an array to a function that expected a string.
