Description

Adds instructions on how to locally install a build of the Python bindings.

Motivation and Context

I want to use a modified version of Selenium locally for a project. I made my changes and followed the build instructions, looked in py/, and saw a setup.py, so figured I could just pip install py/. Unfortunately, that resulted in an error during import that getAttribute.js could not be found. Installing the .whl seems to work fine though, so I'm assuming this is the correct way to do it.
