[Python Version Upgrade]: First Pass at Upgrading Track to use python:3.10.6-slim (#3158)

* First pass at upgrading track to python:3.10.6-slim.
Adjusted GH workflow to use Python 3.10.6 for the CI setup.
Edited pylintrc to omit depreicated check for whitespace.
Checked and pinned library versions for requirements.txt and requirements-generator.txt
Re-tested all exercises to see if they'd explode.

* pylint 2.14.5 needs astroid 2.12.

* Upgraded JinJa2 to latest, pinned astroid to <=2.12.0.

* Dropping support for python 3.6, adding python 3.10.6 to version matrix.

* Pinned version of JinJa2 to 3.1.2
