Hi @AlgoFoe, thanks for addressing this update!

I left a few comments in-line but it should be almost good to go.

I also noticed we should additionally update the license syntax and the build system requirements in the pyproject.toml file of the cookiecutter project itself (this file). Would you mind adding that?

Thanks again!
