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.

Comece pela GitHub branch protection REST API vinculada na issue e determine como as regras de proteção podem ser gerenciadas para vários repositórios. Defina as entradas do script como listas de repositórios e nomes de release; considera-se concluído quando as regras puderem ser atualizadas centralmente sem depender do wildcard release-*, de modo que os pushes de release e as filas de merge funcionem.
