Content Plan Task--Update the contributing.md

[JuLeeAtPlanet]

The current contributing.md file provides information about how to load the development environment. It does not provide any guidance on who might contribute or how to get involved.

This document explains how to generate a local environment and documentation, but does not provide the final locations of the builds and does not instruct on how to view the documentation.

Update the contributing.md file with end-to-end steps to build, change, test, and view documentation.
