Allow creation of new Video Embed Field media entities using the Media Browser

The patch on #32 ✨ Allow creation of new Video Embed Field media entities using the Media Browser Closed: won't fix works fine.

The patch from #32 has one flaw. If the video embed field doesn't have any providers activated, which should allow all of them, no video adding can be done with the form from the patch. The patch fetches the allowed_providers configuration directly. Easy workaround is to enable all providers then.

Used MediaLibraryUiBuilderInterface instead of MediaLibraryUiBuilder to avoid possible errors when using other modules that want to extend the form

New patch resolves the issue in #40.

It's not quite as simple as I thought. One more fix.

Using the MediaLibraryUiBuilderInterface breaks it. Switched back to MediaLibraryUiBuilder.

MediaLibraryUiBuilderInterface doesn't exist yet - https://www.drupal.org/project/drupal/issues/3359354 📌 Add an interface to media_library.ui_builder so the service can be decorated properly Needs work
