[qa] Commit check now work on github actions #163

Closes #163

Changes

Updated the script to check commit messages to work with GitHub Actions.
Used the GITHUB_ACTIONS and GITHUB_EVENT_NAME environment variables to determine if the script is running in a GitHub >Actions workflow triggered by a pull request.
Skipped the commit message check if the workflow is triggered by a pull request.

I think we can just remove those lines. The merge commit exception is already handled in the python code, that if is redundant.
