Add Python Version Matrix Testing to CI

[zacdezgeo]

To ensure compatibility across multiple Python versions, we should update our CI workflow to include a matrix of Python versions for testing. This will allow us to validate the codebase against all supported Python versions (e.g., 3.8, 3.9, 3.10, etc.), ensuring robustness and identifying potential compatibility issues early. Implementing this will improve confidence in the project’s reliability across environments and user setups.
