[pip] Error entering devshell when updating nixpkgs-unstable

[lengyelb-verbund]

When updating my nixpkgs pin, loading a devshell fails with a message similar to NixOS/nixpkgs#420893 (comment)

error: python3.13-PACKAGE-1.0 does not configure a `format`. To build with setuptools as before, set `pyproject = true` and `build-system = [ setuptools ]`.`

This only happens when some company-internal dependencies are used, which are currently being updated to use pyproject.toml and a minimal setup.py. The problem seems to be an update to how nixpkgs python infra works, one potential fix is https://github.com/nix-community/nixos-apple-silicon/pull/315/files
