Investigate a good testing story for testing github workflow change

Currently, we do not have a good way to test github workflow change. We always have to merge it in order to test it. We need to investigate a good test story for this.

Some related work that we may want to look into:
https://dev.to/byteslash/how-to-test-your-github-actions-locally-3830
https://github.com/nektos/act

No files or tests are named. Start by reviewing the linked article and nektos/act to compare ways of testing GitHub workflow changes locally; done would be a documented, validated testing approach for this repository.
