Provide config action to set editor plugin configuration

Added the test, the failed test in the latest pipeline is from block module

Changes are made on on 11.x (our main development branch) first, and are then back ported as needed according to our policies.

There are over 1000 changes in the MR. I think something happened when you switched branches.

Moving to Needs Work.

I have opened the new MR with correct target branch

Looks great. I made one little nit.

Small comments on MR.

Added descriptions

The Needs Review Queue Bot → tested this issue. It fails the Drupal core commit checks. Therefore, this issue status is now "Needs work".

This does not mean that the patch necessarily needs to be re-rolled or the MR rebased. Read the Issue Summary, the issue tags and the latest discussion here to determine what needs to be done.

Looks great.

I read the IS, comments and the MR. I didn't find any unanswered questions or other work to do.

This looks like it's generic for any editor, but it's exposed by the ckeditor5 module and hard-codes itself to only support ckeditor5. Why can't it be provided by the editor module and work generically? If there's a good reason why it can't, then I think the plugin ID should be namespaced to the ckeditor5 module at least, and also the issue summary and inline comments should explain why it's not generic.

The plugin manager that is used in the config action is from CKEditor5 module and it assumes that the plugins will be for CKEditor5. Is there a generic plugin manager for any editor? I think that each editor has its own plugin type, or?
