tests docs: update python3 venv packages
- Package update performed by 1. updating pip, pip-tools, setuptools 2. 'make test-refresh-deps' on ubuntu 22.04 3. fixing 'make test' and 'make docs' issues on ubuntu 22.04 4. 'make test-refresh-deps' on ubuntu 20.04 - Add dependency for 'make test-refresh-deps' to insure python venv is set up. - Update of python formatter, black, caused reformating of 41 python code files. Type: make Change-Id: I7cafdf4b5189065ac57cb6b254937f6e0897a924 Signed-off-by: Dave Wallace <dwallacelf@gmail.com>
