I suppose we need to remove all people who have write access, right? They already get a notification. and also tensorflow/sig-addons-maintainers since it doesn't seem to trigger anything: #1137 (comment)

Thanks this is fantastic!

1. Yeah we'll probably want to remove the duplicate notifications. Do you have a method in mind for doing this? Filtering members of sig-addons-maintainers?

Subsequent PR:

1. Yeah sig-addons-maintainers doesn't actually do anything. We can remove that catch all.
2. We'll need to update the CODEOWNERS to match the README docs. Then we can remove the maintainers from the README so we don't have duplicated work on PRs.

The easiest is to hard-code in the python file the people with write access. This is not public information so I cannot fetch it automatically. I'll add a filter somewhere.

We want to minimize spamming. So the bot will only notify when the pull request is opened. Never after. It's also simpler code-wise.

LGTM Thanks again!
