Delete merged and stale branches from a Github repository.

See example Preview and Cleanup step.

You need to use Python 3.6+ and declare it before

uses: actions/setup-python@v2
with:
    python-version: '3.x'
    architecture: 'x64'

This deletes branches that fulfil either of these:

• Merged into Master or Main (specified by which_master_main) OR
• Branches older than X days (specified by delete_stale_after_days)

This by default does not actually delete until you set parameter action = cleanup

The following branches are not deleted by default:

• main
• develop
• master

WARNING: When you delete branches with no active PR,
you will lose access to the ability to restore the branch.
Please back it up using Github Artifacts or
a copy of the branch prior to running this.
