Integrate module with Content Moderation

I tested patch manually and I still get the "Add" translation operation button, even though there is draft translation there.

I also update the issue description.

Maybe we can try put a check for pending revisions out in a function?

Remove indentention changes.

This patch is working for me.

Updated patch with first attempt to provide translation moderation fields and filters in view.

Thanks!
Adding some configs for tests

Thanks for the updated patch with tests. I looked over and tested it and looks pretty good. I'm making some small updates to the patch. I've turned off sorting for the field as this is not yet supported for moderation states, I've created a follow up issue for that later #3002318: Make translation moderation state field sortable. Also I've updated readme file and made the field title lowercase.

Also make a follow up issue to add translation moderation state filters later:
#3002331: Make a filter for translation moderation states

Thanks for the great work on this!
