fix: improve CI and helper scripts

[WilliamBergamin]

Summary

This PR aims to improve the continuous integration pipeline by breaking up linting, typechecking and testing into separate actions.

This will allow linting and typechecking to run against the latest python and linux runtimes while allowing unit tests to run against all supported runtimes.

The helper scripts were also updated so that they can be used in the continuous integrations without installing unnecessary dependencies.

Testing

CI coverage should be sufficient, but you can run the helper scripts if you want to try them out.

@WilliamBergamin LGTM and thanks for the continued enhancements to CI 👾 ✨

I left a few comments with thoughts, but nothing that blocks this from landing sooner! 🚢 💨

🤖 thought: Keeping all of these workflows within this file might be nice for checking regressions for typechecks, lints, and unittests together?

🐍 ramble: Unsure of a best approach, but sharing an environment variable with the latest python version for the first of those checks might be useful if that seems like it'd be best!

Good point 💯 I've moved the jobs in the same file
