Overview

Thanks @voxpelli for throwing this my way! https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-rulesets/creating-rulesets-for-a-repository#creating-a-branch-or-tag-ruleset

Looks like there's API support: https://docs.github.com/en/rest/repos/rules?apiVersion=2022-11-28

Is this something that we should replace the existing branch protection features with?
