fix: Fixed few `docstrings` according to the Google Style Guide

What does this PR do?

It is mentioned in the Contributing.md file that the Google Style Guide is used for docstrings. I fixed few inconsistencies according the Style Guide.

Used some of the following ruff checks to automatically find and fix these.
