Update advanced backend unit tests workflow and add new Makefile for testing

- Modified the GitHub Actions workflow to trigger unit tests using the new `Makefile.unittests` specifically for the advanced backend.
- Created a new `Makefile.unittests` to define the `test-unit` target for running Python unit tests, enhancing the testing process and organization.
