Remove legacy ckeditor from codebase.

The merge request removes the legacy ckeditor from the codebase

MR!540 changes looks good to me, hence marking this one RTBC.

liam morland → made their first commit to this issue’s fork.

This looks good. RTBC+1

Is there more code that should be removed? I note that _webform_update_html_editor() appears to include a config file that the above commit removes.

This MR removes the left over code.

I noted in _webform_update_html_editor().

The below approach and code can be updated to support ckeditor6 when it is available and required.

Since the tests are passing. I am going to commit this and any additional ckeditor4 issue can be handled in a new ticket.
