Update CKEditor 5 to 38.0.0

Just an observation as this is an expected upstream change but tested and noticed there's a new powered by baloon on editors now. Seems this is an upstream change that affects opensource installs.

Left a comment on 🐛 [Style] Add tests for inability to apply styles to , , , etc. in CKEditor 5 — and allows applying it to all elements Fixed where I found a bug.

But overall ckeditor update appears to be working. Haven't found a regression. Since ckeditor_styles almost doesn't work this works better even if it's got a bug or two.

Committed and pushed 47c4939fec5 to 11.x and eb08f0528da to 10.1.x. Thanks!

Also updated the release notes.

Automatically closed - issue fixed for 2 weeks with no activity.

Is there any chance of this being applied to the 9.x branch? We're still a couple months out from moving to 10.x but I'd like to roll the Ckeditor5 upgrade out sooner if possible. If not, what is the recommended method for changing to a custom build of ckeditor5?
