Ideally all help_text shall move to forms, so we don't get new migrations every time we want to edit text. Here I pointed to only those related to ckeditor, as it is now the focus, and we may be asked to change it again soon.

the help texts are done in #5412 once that is merged I will recreate the migrations here so they don't include the helptext anymore

Looks good.
So now this PR needs to wait for the A4 squashing migrations?

If you mean the migrations from the two a4 PRs we talked about earlier, they are squashed already
