Github action => Slack

[mattwynne]

It would be amazing to have a GH action that can push a message to Slack when there's a new file in the retros folder.

@mattwynne yes this would be great.

I'm not super up on GH actions. Can we build one that lives in this repo that others can install?

[mattwynne]

I have no idea! But I think we should try.
