Add message to vbo workflow transition

Before:

After:

Thanks for the patch @jwilson3!

I think this is a great default message. And if anyone does not like this, particularly if you transition a ton of content at once it will make a lot messages, you can also override the message in the views configuration if one would like:

woah. thanks @mattsqd for the responsive reply, review, and merge. 🙌

Can you manually add @marthinal to the issue for credit 🙏

He originally wrote the patch which we were using internally on a project.

mattsqd → credited marthinal → .

No problem!
