Updating core to 10.3 breaks CKEditor

This is temporary solution for review because I don't have the original ckeditor_templates.js.

For some reason can't apply #6.

I have the same problem where CKEditor 5 broke when I upgraded Drupal to 10.3.

I do not have ckeditor_templates_ui installed though. I know this issue is for ckeditor_templates_ui but I believe this is a wider issue affecting more CKEditor modules.

In case this is still helpful for future resolution, my error is:

ckeditor5.js?sfp0r8:468 CKEditorError: plugincollection-plugin-not-loaded {"plugin":"TrackChangesEditing"}
