Use pip 23.2 and setuptools 68.

See pip changelog. Of interest:

• Fix slowness when using importlib.metadata (the default way for pip to read metadata in Python 3.11+) and there is a large overlap between already installed and to-be-installed packages. That was my fix.
• freeze no longer excludes the setuptools, distribute, and wheel from the output when running on Python 3.12 or later, where they are not included in a virtual environment by default. Use --exclude if you wish to exclude any of these packages.

And see setuptools history. This removes several items that were long deprecated. Nothing that immediately stands out for me.
