Add CKeditor 5 support

Assigning that to myself will allow me to explore the CK5 API and an in-depth understanding of the CK4 integration.

HI Naveen, I'm already working on it and I have a work in progress module.

That's excellent news, Eleo!

I just tried Augmentor on Drupal 10 which comes with CKEditor 5 out of the box. So it's not really possible to test anything without this. Thanks for working on it.

@bogdog400 But in Drupal latest 9.x version, Augmentor is still not compatible with CKEditor 5, which is enabled by default.

Ready for review.

It appears that not only does Augmentor only support CKeditor 4. It actually requires CKeditor 4 to be selected on the pages on which there is an Augmentor edit form widget. I tried numerous variations on a clean install.

I tried numerous variations in a clean install:
CKeditor 4 enabled, but not selected as the editor for a formatted textarea element.
CKeditor 4 and 5 enabled, but CKeditor 5 selected as the editor.
CKeditor 4 enabled, but no editor selected.
CKeditor not installed at all.
CKeditor 4 enabled and selected as the editor for at least one textarea.

The only variation that works is the last one. If CKeditor 4 is not loaded on a page that has an Augmentor widget, the following JavaScript error is thrown when clicking on the Augmentor widget button:

[Error] ReferenceError: Can't find variable: CKEDITOR

Thanks @hyperlinked,

I created a separate issue for that, please check https://www.drupal.org/project/augmentor/issues/3358019 ✨ Separate Ckeditor 4 in a submodule Fixed
