refactor: stop using private pypi (#132)

* refactor: stop using private pypi

This was required because our repos were not public. Now that they are, people can directly access our Python packages and therefore they don't need access to our private codeartifact anymore

* docs: add a list of dependencies in the readme and early check in the setup env script
