 If you want the same limit for both concurrent branches and concurrent PRs, then just set a value for `prConcurrentLimit` and it will be reused for branch calculations too.
 However, if you want to allow more concurrent branches than concurrent PRs, you can configure both values (e.g. `branchConcurrentLimit=5` and `prConcurrentLimit=3`).
