Update the nix-shell environment (#13316) * Nix: Allow calls to `bin/qmk` even when the build was started by `qmk` The `$PATH` modifications performed by the Nix wrapper for the `qmk` executable prevent `bin/qmk` from working properly (the changed `$PATH` contains a wrong `python3` executable which does not have the needed Python modules in its module path). As a workaround, disable the generation of that wrapper for the `qmk` Python package (there is yet another wrapper generated while building the Python environment, which would still set the Python module path properly when running `qmk`). Although `bin/qmk` is officially deprecated, QMK CLI still invokes it in some cases (at least `qmk doctor` and `qmk pytest`), therefore keeping these invocations working is useful. * Nix: Update `util/nix/pyproject.toml` to match `requirements*.txt` Update the Python dependency information used by Poetry to match the current state of the qmk_firmware code. * Nix: Bump QMK CLI dependency to 1.0.0; bump other Python deps Update Python dependencies for nix-shell to the most recent releases: - dotty-dict: 1.3.0 -> no longer used - milc: 1.4.2 -> 1.6.2 - pep8-naming: 0.11.1 -> 0.12.1 - pygments: 2.9.0 -> 2.10.0 - pyrsistent: 0.17.3 -> 0.18.0 - pyusb: 1.1.1 -> 1.2.1 - setuptools-scm: 6.0.1 -> no longer used - qmk: 0.1.0 -> 1.0.0 - qmk-dotty-dict: not used -> 1.3.0.post1 - yapf: 0.30.0 -> 0.31.0 Note to self: The command to update Python dependencies changed to: ( cd util/nix && nix run 'nixpkgs#poetry' -- update --lock )
