Document GitHub Configuration

[frozenfrank]

Overview

We have employed many powerful and helpful configurations in this organization. While they are all for the benefit of overall collaboration, new users may not be familiar with them.

We want to describe what is going on in the org, why it is happening, and how to become a contributor.

Details

Cover the following:

• Repo overview
• Teams overview
• Branch protection strategy
• autograder dependencies
• Related resources

Also give a callout to these materials from the landing README.md file. This gives future TAs a chance to discover the information.

I still believe this should be done but I don't actually know enough to write this.

@softwareconstruction240/professors and @softwareconstruction240/tas? Opinions on this issue and who could work on it?
