Tools: install-prereqs-ubuntu.sh: fix script after setuptools==71.0.0…

… release

Use newest `packaging` to avoid packaging incompatibility with `setuptools>=71.0`

As pypa/setuptools#4496 (comment) mentions:
> setuptools>=71.0 does not work with packaging<24.0, but will not upgrade it if packaging is already installed

Also relevant: pypa/setuptools#4496
