Add pre-commit tool

[KAUTH]

In this commit, we add the pre-commit tool to improve the Software Development Lifecycle of the project by automatically running checks (linting & formatting) before one commits their changes.

Specifically:

• we added a local hook with pre-commit that calls tox to lint and format Additionally, the check-added-large-files commit hook was added (prevents giant files from being committed).

• We fixed doc build and pylint failing:

• Docs were failing with the pinned versions of their dependencies (sphinx, sphinx-autodoc-typehints). So we unpinned the dependencies (also good as best practice).

• Pylint was not able to read the sections related to its configuration in tox.ini. So we added a pylint section in tox.ini with the necessary key/value entries.

• We updated the CONTRIBUTING.md with how to install pre-commit
