Pin version of setuptools to support pkg_resources API

[tcv-git]

Description

The script tools/check_python_dependencies.py uses the pkg_resources API, which was deprecated in Python 3.12 and has been removed in setuptools version 81.

This makes the export.sh script unusable.

Updating requirements.txt to versions older than this fixes the problem.

Testing

Run install.sh and then source export.sh. It now reports success.

I've had to do this as well, and actually it works with setuptools<82 too.
