Fix llm tool installation - update nixpkgs hash in Biz/Bild.nix

The fix is complete. Changed `python311.withPackages` to
`unstable.pytho

1. `python312` has the proper `llm` override defined in
Python.nix 2. `python311` only overrides `llm-ollama` and
`llm-sentence-transformer 3. Using `unstable` is consistent with
other AI tools in the same sectio
