Describe the improvement

I'd like to adhere all of our guides, including the Python Starter Kit, to leverage our new infusion strategy "standards as code". See here.

For the Python Starter Kit, this means we should see which elements can be extracted and presented in a way that:

1. An existing project can infuse the CI/CD aspects
2. SLIM can use the leaderboard infrastructure to push out proposal pull requests for the Python starter kit elements
