chore: remove temporary debugging logic to push to PyPI

[FelixS90]

[x] I followed the How to structure your PR.
[ ] Based on Commit Parsing: In case a new major release will be created (because the body or footer begins with 'BREAKING CHANGE:'), I created a new Jupyter notebook with a matching version.
[ ] Based on Commit Parsing: In case a new minor/patch release will be created (because PR title begins with 'feat'/('fix' or 'perf')), I optionally created a new Jupyter notebook with a matching version.
[ ] In case of API changes, I updated API.md.

Remove debugging code for temporaily pushing to testpypi until infrastructure properly set up.
