[Feature]: Python kernel without poetry

[MMesch]

What's missing?

I'm looking for a way to add python packages without poetry. Is this possible?

Possible solution

Expand the python kernel to accept poetry or non-poetry packages.

Alternatives

Have two separate Python kernels available. One for poetry and another without.

Additional context

No response

poetry2nix support extraPackages argument which can be used to add python packages (those packaged with Nix).

But last time we tried it we hit a bug, which led us to another bug, so we never really confirmed that this works.

The idea was that initial template would show how to add more python packages (those already existing in nixpkgs).

I personally think not supporting pure nix kernel definitions is very limiting for those already familiar with nix ecosystem. While poetry might be very popular I personally use nix exactly to avoid dealing with poetry in the first place because it is an inferior tool imo.

I propose clarifying whether extraPackages works as of now and making it very clear in the docs that jupyenv currently does not aim to support nix-defined kernels but, possibly, allows for bringing in already nix-packaged python packages via extraPackages (if this is the case). If the latter is supported there should be an example in the docs and a test case.

Happy to help with some of the above.
