Make this repository public

Is there a good reason not to?

I've also heard from new hires that it was comforting to be able to learn about our onboarding procedures publicly accessible on the Hub before they started.

I also recently made a USDS staffer's day by showing him the Hub; being able to show it publicly helped to address a shared need.

The plans are to make this public, yes - waiting on some QA'ing - because there is the potential to share internal info here.
