Auto-update plugin docs versions

[samwestmoreland]

This replaces the docs plugin version lint action with a cron job that runs every morning at 9 that should create a pull request to update the versions if needed. Not really sure how to test it!

Have you been able to test this at all?

What does this line do?

[samwestmoreland]

That apparently allows manual triggering of the action

I haven't... yolo? Will revert if it's not working!

Oh, I just saw your "Not really sure how to test it!" comment. In theory you could save (most of) the shell commands as a script and run it locally, but practically I don't think this can do much harm so we can just test "in prod" as it were

Ah good point! The file update part at least seems to do the job:
