Update to CKEditor v40 for the multiBlock option

[MoritzLost]

Description

We need the multiBlock option to limit author's ability to enter multiple blocks / paragraphs in a list. This is supported in CKEditor 40:

• https://github.com/ckeditor/ckeditor5/releases/tag/v40.0.0
• Document lists should have a “simple list” config option ckeditor/ckeditor5#14634

However, the plugin is currently on CKEditor 39.0.2, so we can't use that option.

Bumping the CKEditor version would be greatly appreciated – thanks!

Additional info

• Craft version: 4.5.6.1
• PHP version: 8.2
• Plugins & versions: CKEditor 3.6.0

This would also cleanup the choice between list types:

Hi both! Thanks for the nudge. I raised a PR to update to the latest CKEditor, switch to TodoDocumentList plugin and remove the no longer needed lists v1.

CKEditor 3.7.0 was just released, with CKE 5 41.0.0, plus TodoDocumentList has been pulled in, and List, ListProperties, and TodoList have been removed.

@brandonkelly @i-just Thanks! 🚀

Is it normal that the listPlugin key remains in the config object with an empty string value in config/project/ckeditor after saving the CKEditor configs?

That was overlooked, but I’ve fixed it for the next release (cd196c3).
