feat(Drupal 10 Support): apply patches and improve logging

This updates the module for Drupal 10. We didn't require any big code changes. I also added some improvements to add types. This requires at least PHP 7.4 so I bumped that up. The newer Drupal at least require PHP 8 so we could probably go higher but I couldn't 100% for old Drupal 8 versions.
