Update CKEditor 5 to 41.2.0

Copy/paste leftover 🤣

Based on the results from January 29 over at #3379104-35: Add a "CKEditor 5 nightly" GitLab CI job → , I already know tests will fail. 😮‍💨

Well that was easy 😄

In a meeting with the CKEditor 5 team just now, there's going to be a 41.2.0 release next week, so let's wait for that 👍

https://github.com/ckeditor/ckeditor5/releases/tag/v41.2.0 is out 👍

Some very interesting new things:

1. CKEditor 5 v41.2.0 introduces the Accessibility Help Dialog, which is something CKEditor 4 also used to have!
2. link: Added the ability to specify allowed URL protocols by introducing the link.allowedProtocols configuration property. Closes #14304. (commit) -> doesn't really affect us because the default (only allowing HTTP/HTTPS/MAILTO) has served us fine so far. But a contrib/custom module may have additional needs, so then this makes sense 👍
3. html-support: Background color style should be properly preserved by GHS while the FontBackgroundColor plugin is enabled. It should also be able to preserve a partly defined style. Closes #15757, #10399. (commit) → I'm sure this will help sites with … more "complex" content
4. paste-from-office: It now should be possible to paste charts from Microsoft Word. Closes #15758. (commit) → surely an important fix for some
5. source-editing: Source editing should not add whitespaces to the pre-formatted code lines. Closes #15084. (commit) → reported by yours truly: https://github.com/ckeditor/ckeditor5/issues/15084 🤓

MR is applied and working well.

Updated MR to fix deprecation notices:

Question:
new AccessibilityHelp component of CKEditor - how should that be implemented? Added to the core just like other components? or a separate contrib module?

Question:
Is this going to be backported to D10.2/3?

@jannakha Ohhhh! Well-spotted! Thank you 🫣🙏😄

RE: AccessibilityHelp: I contemplated doing that. I was thinking it'd be preferred to do that in a follow-up issue, because we may want to change the Standard install profile's default text editors to have this button enabled by default…

RE: 10.2/10.3: this will land in 10.3 for sure, because 10.3.0 has not been released yet. This will not be backported to 10.2.0, because it's a major version bump of CKEditor 5, and includes breaking changes.

@Wim Leers!
awesome! I'll test this MR more on my sites to get this released sooner!

I've created a new task for AccessibilityHelp so it can be developed independently from this issue: https://www.drupal.org/project/drupal/issues/3427039 ✨ Implement AccessibilityHelp plugin for CKEditor5 Active

Thanks, @jannakha! Followed up on that issue.

This issue is now ready for RTBC — and I think @jannakha is uniquely qualified to do so, because she spotted the thing I overlooked! 😄👍

So I applied the MR locally this morning.
Did some content creation in the ckeditor, using all the buttons I can.
I see drupalmedia changed so I tested embedding media bundles in the ckeditor and that was still working for me.

Update seems fine +1, but will leave in review for additional eyes.

Tested again today and still not seeing any regression.

Thanks for the testing, makes sense to get this in asap so it's available during the alpha and later. Added to the 10.3.0 release notes draft.

Committed/pushed to 11.x and cherry-picked to 10.3.0, thanks!

Seems also translations should be added
After i runned yarn build

Oh weird … you're right: 🫣

$ git status -- core/assets/vendor/ckeditor5/
On branch 11.x
Your branch is up to date with 'origin/11.x'.

nothing to commit, working tree clean

$ yarn --cwd core build
<SNIP>

$ git status -- core/assets/vendor/ckeditor5/
On branch 11.x
Your branch is up to date with 'origin/11.x'.

Untracked files:
  (use "git add <file>..." to include in what will be committed)
	core/assets/vendor/ckeditor5/autoformat/translations/

nothing added to commit but untracked files present (use "git add" to track)

The testUnmanagedGitIgnoreWhenGitNotAvailable failure is happening all across core; that's unrelated to this MR.

Repeated #23 locally on top of the branch that @finnsky pushed, and confirmed that I get identical results.

⚠️ I've updated the issue summary to ensure the next CKEditor 5 update doesn't repeat this mistake.

Committed/pushed to 11.x and cherry-picked to 10.3.x, thanks!

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

Removing tag because CKEditor was updated later, 📌 Update CKEditor 5 to 41.3.1 Fixed
