Support for block content entity

MR created.

I have update some tests by searching for occurrences of Media.

In previous comment is attached screenshots showing the result.

Thanks a lot for the service to update entity definition, really helpful.

I guess there will be other stuff to update, tests?

I tested the fork, but the only way that I could get this to work properly was to also enable the content moderation workflow and add a content block type to the workflow. I'm assuming this is is related to ✨ UI for publishing/unpublishing block_content blocks Needs work because blocks don't expose the publish status checkbox and are always published. Am I correct in this assumption and setting this up or did I miss something somewhere?
