Support CKEditor5

Have made a good start / proof of concept on the MR.

Ready for review - ran out of time for tests today - keen on initial feedback before pushing futher.

Attached stable patch for use with composer.

Thank you ericgsmith. I like the solution. I'll try to review it and merge asap.

This appears to work really will, thank you.

I tidied up the README.md file a little.

Tested and it does seem to work nicely. Thanks!

One possible improvement could be the ability to specify a form display mode in the settings for editing the modal.

@loze: That's a great idea, but I think it could be done in a separate issue.

In testing we noticed that the edit icon shows for media items even if the user doesn't have access to edit the specific media item; this is a common problem when some roles have permission to edit media they personally upload but not all media. Right now if a user in this situation clicks the edit icon they don't see anything - there's a console message (403 error from the request) but they don't know what's going on.

FYI when using this patch you might run into a core bug: 🐛 Why does Route access checking differ from Entity access checking? Needs work

Is there any way to hide the icon if the person doesn't have access? From what I can see it always shows the icon and then core fails to handle the permissions properly on the AJAX callback.

I think this could be committed as-is with a note about permissions, and then the icon permissions handled separately as I suspect most sites will be ok with it.

This repalces the permission check so it checks "update" instead of "edit".

I can confirm that the patch from #12 works as expected.
Thanks!

Patch #19 with the access check change is working very well for us.

+1 for patch in #19. Thanks guys!

Thanks @DamienMcKenna for the fix on the access!

Closing MR and hiding old patches so latest patch is clear.

+1 for #19 thanks
