Detect ruleset diff based on the branch pattern #2211
Description
As encountered in the PR #2200 (comment)
The current logic matches rulesets by name, so when the name format changed from "Branch protection for main" to "Ruleset for main", it can't find a match and ends up deleting + recreating instead of updating.
Expectation is
- The ruleset will be updated (including renaming from "Branch protection for main" to "Ruleset for main") instead of being deleted and recreated
- Only if the branch patterns don't match will a new ruleset be created
- If an existing ruleset on GitHub protects
refs/heads/main, and the expected ruleset also protectsrefs/heads/main, they'll be matched together
