[Bug]: Can't update poetry2nix version to the latest due to refactor of poetry2nix

[silky]

Current Behavior

You can't update the version of poetry2nix because of how poetry2nix is invoked.

Here: https://github.com/tweag/jupyenv/blob/main/modules/poetry.nix#L51

poetry2nix is passed poetry; but this is no longer supported - https://github.com/nix-community/poetry2nix/commit/fb135081ec78e42f1c36a030c03e5bdb083e5486

Expected Behavior

You can use the latest poetry2nix

Steps To Reproduce

Explicitly ask jupyenv to follow the latest poetry2nix:

  inputs.poetry2nix = {
    url = "github:nix-community/poetry2nix";
    inputs.flake-utils.follows = "flake-utils";
    inputs.nixpkgs.follows = "nixpkgs";
  };

  inputs.jupyenv = {
    url = "github:tweag/jupyenv";
    inputs.poetry2nix.follows  = "poetry2nix";
    inputs.flake-utils.follows = "flake-utils";
    inputs.nixpkgs.follows     = "nixpkgs";
  };

OS

- system: `"x86_64-linux"`
 - host os: `Linux 6.1.21, NixOS, 22.11 (Raccoon), 22.11.20230325.83607da`

I can only guess that the reason to pass in poetry explicitly was to set the python version? so maybe there's an alternative way of doing that?
