ChatQnA urllib3 old version

[wsfowler]

Following the readme for the ChatQnA Gaudi example and ran into the following error during step 1:

Installed /usr/local/lib/python3.10/dist-packages/mypy_extensions-1.0.0-py3.10.egg
error: urllib3 1.26.5 is installed but urllib3>=2 is required by {'types-requests'}

This is during the python setup.py install step.

Fix was to use pip to install a 2.x.x version of urllib3.
