Summary
Fixes #1650
This PR implements the feature requested in #1650 by adding a new environment
variable
PIPX_DISABLE_SHARED_LIBS_AUTO_UPGRADEthat allows users to disableautomatic upgrades of shared libraries (pip, setuptools, wheel).

can encounter errors when pip automatically upgrades to versions that no longer support
their Python version. This environment variable provides a way to disable the automatic
upgrade behavior while still allowing manual upgrades via
pipx upgrade-shared.Changes Made
