Add integration tests to make sure the post install scripts are tested on commit

These scripts are used in workshops and other places like blogs. We want to make sure these scripts continue to work after a change

Start by reviewing the repository's post-install scripts and any existing test or commit-check configuration. Determine how the scripts are expected to run in workshop and blog use cases, then define integration checks that execute them and verify they continue to work after changes.
