python312Packages.nicegui: pattern setuptools does not match

[belamu]

Nixpkgs version

• Unstable (25.05)

Describe the bug

When including python312Packages.nicegui, I get the error

error: builder for '/nix/store/iapscknypz8hjb3p74qa7wy5x77905l0-python3.12-nicegui-2.9.1.drv' failed with exit code 1;
       last 19 log lines:

       > Running phase: patchPhase
       > substituteStream() in derivation python3.12-nicegui-2.9.1: ERROR: pattern \"setuptools\>=30.3.0\,\<50\"\, doesn't match anything in file 'pyproject.toml'
       For full logs, run 'nix-store -l /nix/store/iapscknypz8hjb3p74qa7wy5x77905l0-python3.12-nicegui-2.9.1.drv'.
error: 1 dependencies of derivation '/nix/store/mb4a401r2xrnkd9faz77yksf11s0y8cl-python3-3.12.8-env.drv' failed to build

The error message is correct, since the code in nixpkgs is

  postPatch = ''
    substituteInPlace pyproject.toml \
      --replace-fail '"setuptools>=30.3.0,<50",' ""
  '';

while the interesting lines in the pyproject.toml are

[build-system]
requires = [
    "setuptools>=30.3.0",
    "poetry-core>=1.0.0"
]
build-backend = "poetry.core.masonry.api"

since a commit, that removed the <50

Steps to reproduce

shell.nix:

{ pkgs ? import <nixpkgs> {} }:
pkgs.mkShell {
    packages = with pkgs; [
      (python312.withPackages (python-pkgs: with python-pkgs; [
        nicegui
      ]))
    ];
  }

and run nix-shell while your update-channel is unstable

Expected behaviour

The package is built.
