chore: dependencies = setuptools for gyp --version on Python >= 3.12

[cclauss]

On Python >= 3.12

% pipx run --no-cache --spec git+https://github.com/nodejs/gyp-next.git gyp --help was erroring with

ModuleNotFoundError: No module named 'packaging'

% pipx run --no-cache --spec git+https://github.com/nodejs/gyp-next.git gyp --version is still erroring with

ModuleNotFoundError: No module named 'pkg_resources'

gyp --help was fixed in gyp-next v0.18.0
gyp --version was not

Since both modules are included setuptools let's use that recommended fix.

---

Proof:
% pipx install gyp-next
% gyp --version # Fails!
% pipx inject gyp-next setuptools # This is the same action as this pull request.
% gyp --version # Works as expected.
% gyp --help # Works as expected.

I believe packaging should not be removed as installing setuptools doesn't come with packaging.

Suggested change

	dependencies = ["setuptools>=69.5.1"]
	dependencies = ["packaging>=24.0", "setuptools>=69.5.1"]

Downloading setuptools-69.5.1-py3-none-any.whl from https://pypi.org/project/setuptools/#files and unarchiving it, I didn't find that packaging is included in setuptools.

Let’s not have three copies of packing…

Yes, packaging is vendored in setuptools. But as far as I could tell, packaging in setuptools is not exposed in site-packages with setuptools. So it would need to import like from setuptools._vendor.packaging.version import Version.

@cclauss I created a github action to verify this change: https://github.com/legendecas/gyp-next/actions/runs/9127187853
