Check commit messages

This action checks the commit messages on a branch to ensure they follow the Conventional Commits specification. It assumes Python, pip and Commitizen are already setup, see the setup Python action and setup Commitizen action for ready to use actions to do this.

There is also a ready-to-use workflow that uses this action.
