Enable action installation on multiple repos

[laurentsimon]

Organizations and users may want to enable an action at scale on multiple repos. This requires

1. creating a PAT
2. saving as secrets in each repo
3. Creating pull requests

@josepalafox is there an org setting to enable a workflow at scale?

I'm going to take over cleanup of the multi-repo-action.

@justaugustus are you still planning to work on this? Would be good to announce this tool along with our v2 launch (aiming for a launch timeline of first week of September). Let us know if you need help or are unable to work on this.

You could probably automate several of the setup steps using something like Terraform for GitHub.

Yep, I can work on this before then!
