Use python3 in the system environment
Some user setups are expecting to use a python in a different location
than /usr/bin, and an older python interpreter may be present at that
location (Rocky Linux 8 being one), causing issues (notably that
shutil.copytree does not have dirs_exist_ok keyword parameter in
Python versions < 3.8).
This uses the python3 interpreter that is in the shell's current PATH,
instead of hard-coding it to /usr/bin/python3.
