make_packages.sh fails on python3.12

[accumulator]

python 3.12 removed some deprecated symbols, resulting in AttributeError: module 'pkgutil' has no attribute 'ImpImporter'. Did you mean: 'zipimporter'? when running make_packages.sh

See https://docs.python.org/3/whatsnew/3.12.html#importlib

I updated pip and setuptools pinned versions in deterministic-build/ (https://github.com/accumulator/electrum/tree/python312_setuptools), but freeze_packages only yields me a single hash, not exactly sure why..
