Add tool to manage branch protection rules across many repositories

We currently have a branch protection rule in place that protects "release-*" branches in our repositories.

This has drawbacks:

• it will cause release scripts to fail because the newly created release branches cannot be pushed to by the script
• prs on these branches cannot use the merge queue (not possible with wildcards in the branch name)

It might be worth switching to individual protection rules for every release, but that would make them hard to change/administer.

The github api allows managing these rules: https://docs.github.com/en/rest/branches/branch-protection?apiVersion=2022-11-28

We should look into writing a simple python script that takes a list of repos and release names and updates these protection rules.

Commencez par la GitHub branch protection REST API liée dans l’issue et déterminez comment les règles de protection peuvent être gérées pour plusieurs repositories. Définissez les entrées du script comme des listes de repositories et de noms de release ; le travail est terminé lorsque les règles peuvent être mises à jour de manière centralisée sans dépendre du wildcard release-*, afin que les pushes de release et les files d’attente de merge fonctionnent.
