Support props that can use wysiwyg widgets

Not much point working on this until we can get CKEditor 5 loading on textareas 📌 CKeditor not loading on formatted text fields in the content entity + component instance forms Active so postponing on that

The current MR is outdated to the point that it's probably not worth continuing, and will likely be less relevant after #3512867 so I'm going to hide that one and recommend a new MR starts once we have CKEditor 5 working in the fields that are configured to use it. #3512867 already has it the editor properly loading with formatted text fields in the Page Data form
