Add 2.x branch for drupal:ckeditor5 compatibility

Confirming this is a major issue. When using composer require drupal/ckeditor_paste_filter it leads to:

while ckeditor 5 is already part of core.

Could you please remove that dependency asap and create a new release?

If needed, split Drupal 10 compatibility from Drupal 9 compatibility by separate releases (2.x). Thanks!

Change dependency from drupal:ckeditor to drupal:ckeditor5 instead. See the MR. Removing the dependency would be wrong.

Does this module work for CKEditor 5?
