make a derivation that symlinks everything you want from your {python_env}/bin to it's $out/bin?

I have a strange thing happening in one of your projects, maybe someone of you has an idea what is happening.
We basically have the following configuration.
It is a project where we use Ansible and Ansible Molecule for testing.
In the dev shell everythin feels normal.
When we have a look at ansible-playbook it seems to be a binary.

Recently we created a custom Ansible module with additional dependencies.
They work fine wenn we run it directly from the within the dev shell.

But when run Molecule tests (a container based test framework) the path to ansible-playbook in the store is different and it is now a bash script.
Inside which it points to a different Python version which then doesn't have our required dependencies.

Everything gets installed through poetry2nix so I'm a bit lost why it should be different between the dev shell and molecule.

system = "x86_64-linux";
pkgs = inputs.nixpkgs.legacyPackages.${system};
poetry2nix = inputs.poetry2nix.lib.mkPoetry2Nix { inherit pkgs; };
python = pkgs.python310;
root = ./.;
pythonDevEnvironment = poetry2nix.mkPoetryEnv {
  groups = [
    "main"
    "dev"
  ];
  projectDir = root;
  inherit python;
};
