[FR] Update platformdirs to 4.2.2

[youknowone]

What's the problem this feature will solve?

Current version of setuptools requires ctypes to run on windows.

Describe the solution you'd like

The hard dependency of ctypes came from platformdirs. Since platformdirs released a new version including the required change, upgrading platformdirs to 4.2.2 will fix the issue.

Additional context

Hi, I am a developer of RustPython, which does not support ctypes yet. This fix will allow RustPython to access most of packages packaged with setuptools on PyPI.

@youknowone as of 71.0.0

setuptools will prefer installed dependencies if present

I think this offers a path by installing / pre-installing platformdirs>=4.2.2 before setuptools>=71 (although I agree it would be nicer if your users didn't have to).

Thank you so much! I didn't think of that since it was vendored.

Looks like https://github.com/pypa/setuptools/commit/4f6d97344c9e15c643aa3e366b21377a2008bc11#diff-6f6b1498bf597f61de49548bf7618ef15201dd95f0cf9fffa36e357dc802353bR15-R16 also updated the vendored version of platformdirs to 4.2.2

So if it's not already installed, it should work fine, and if it's pre-installed, the current requirement of platformdirs >= 2.6.2 should match 4.2.2 when upgrading.

So if pip install setuptools[core] --upgrade doesn't work, running pip install platformdirs>=4.2.2 first ought to work.

@jaraco Do you think it's worth bumping the declared platformdirs dependency for this ? To help platforms lacking ctypes support install setuptools seamlessly ?

I'd be fine with that.
