This PR introduces the ability to set audit exceptions for the autobump workflow in homebrew/cask. There are some audit failures that are easily remedied, and it should be easier from a maintainability point of view to fix them in a PR with 🟥 CI than having to discover them in the autobump workflow logs.

An alternative could be to collect the exceptions from an environment variable that is set in the workflow, which could make it easier to update the list without having to find it in the homebrew/Brew code. I can update if this is preferable.

Pull Request Overview

This PR adds support for audit exceptions in the bump-cask-pr command to handle known audit failures during the autobump workflow. When the HOMEBREW_TEST_BOT_AUTOBUMP environment variable is present, the min_os audit check is automatically excluded.

Key Changes:

• Added audit_exceptions parameter to run_cask_audit method with conditional min_os exception
• Updated method signature and type annotations to support the new parameter
• Modified audit command to include --except flag with comma-separated exceptions
