Branch nhjohnstone/issue-1001-switch-to-ck-editor-5 created!

ran into some issues that are related to Drupal 10.3 update (or 10.2):

before switching to ckeditor 5, had to remove "class" and "start" from the tags in allowed html tags

Linkit Media Library button is not working, due to a Drupal 10.3 change
https://www.drupal.org/project/drupal/issues/3446026

I added the patch so we could see the button, but we might want to remove it if this doesn't get fixed.
Linkit Media Library is not being maintained
