Our release branches follow the pattern release/v* but this doesn't work with Probot + .github/settings.yml. Ref: repository-settings/app#227 (comment)

Possible solutions:

• generate branch protection rules for possible release branch explicitly release/v[1-30]. This would clutter the web UI for branch protections.
• manually configure branch protections for each actual release branch. Tradeoffs: error prone and possible to forget or misconfigure some settings
• Require configuration in template-oss for each required release branch. Less error prone, but still possible to forget.
