Content Moderation should only validate its own workflow type

This should do it.

This validation tested in \Drupal\Tests\content_moderation\Kernel\ContentModerationWorkflowConfigTest::testDeletingStateViaConfiguration(), but I don't think that adding specific test coverage for this bug would add any real value to that test.

Believe it makes sense to only operate on content_moderation plugins in the content_moderation module. M

I'm triaging RTBC issues → . I read the IS and the comments.

The only question here is whether a test is needed. By current policy a test is needed but I understand the point made in #2. I'll leave this at RTBC and let another committer express an opinion.

Yeah I agree the extra coverage is not useful here - we'd be testing that something that used to happen doesn't happen any more, but not actually adding more code coverage - the new condition is covered by the existing coverage.
