Subject: [PATCH] Add Docker Github Action (#2086)

* Add Docker Github Action
- Build and upload arm64 + amd64 black images on push to master

This will need a `DOCKERHUB_USERNAME` and `DOCKERHUB_TOKEN` secrets set by someone with access.

* Change tag to push to pyfound/black repository. Thanks @ewdurbin
