chore: add branch protection rules

[lprimak]

This is the response to ASF Infra's security tightening initiative.

Following this checklist to help us incorporate your contribution quickly and easily:

• Make sure there is a GitHub issue filed
  for the change (usually before you start working on it). Trivial changes like typos do not
  require a GitHub issue. Your pull request should address just this issue, without pulling in other changes.
• Format the pull request title like [#XXX] - Fixes bug in SessionManager,
  where you replace #XXX with the appropriate GitHub issue. Best practice
  is to use the GitHub issue title in the pull request title and in the first line of the commit message.
• Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• add fixes #XXX if merging the PR should close a related issue.
• Run mvn verify to make sure basic checks pass. A more thorough check will be performed on your pull request automatically.
• Committers: Make sure a milestone is set on the PR
• Committers: Use "Squash and Merge" to combine all commits into one when merging a PR when appropriate.

Trivial changes like typos do not require a GitHub issue (javadoc, comments...).
In this case, just format the pull request title like [DOC] - Add javadoc in SessionManager.

If this is your first contribution, you have to read the Contribution Guidelines

If your pull request is about ~20 lines of code you don't need to sign an Individual Contributor License Agreement
if you are unsure please ask on the developers list.

To make clear that you license your contribution under the Apache License Version 2.0, January 2004
you have to acknowledge this by using the following check-box.

• I hereby declare this contribution to be licenced under the Apache License Version 2.0, January 2004
• In any other case, please file an Apache Individual Contributor License Agreement.

I wish we could to true, true, 1. But I see that is currently not possible, so... works for me!

        includes:
          - "main"
          - "release/*"

I haven't seen any other maintenance branch we would need to include. So, works for me (but please double check)
