Add Automatic Handling of GitHub Actions Tag

[blink1073]

Problem

We are currently using a custom script here and in maintainer-tools to manage GitHub Actions tag.
We also want to be able to quickly roll back a tag if we make an errant release.

Proposed Solution

• Add config for the current GitHub Actions tag, and automatically manage that tag when making a release.
• Add a _prev label to the previous tag location
• Add a workflow to roll back to the _prev tag for the current release given a target repo
