Missing docstring in public module

🐞 Problem
One of the requirements of code style checkers is that all Python modules should contain a docstring at the very top of the file.

Currently, the following files are missing such docstring:

src/ansys/stk/core/graphics.py:1:1: D100 Missing docstring in public module
src/ansys/stk/core/internal/coclassutil.py:1:1: D100 Missing docstring in public module
