 """
 Update .github/ configuration files on ``main`` when a new major/minor
 release branch (vX-Y-test) is created.

 Adds the new branch to dependabot, milestone-tag-assistant, basic-tests,
 ci-notification workflows, boring-cyborg auto-labelling, and the
 README.md build status badge.

 Usage::

     uv run dev/update_github_branch_config.py <NEW_MAJOR> <NEW_MINOR>

 Example — after creating the v3-3-test branch::

     uv run dev/update_github_branch_config.py 3 3
