Move "Getting Started" to the first page

jyn514 · jyn514 · commit 6a1daff55a74 · 2023-04-08T12:20:01.000-04:00
This page is better suited for people landing immediately from
CONTRIBUTING.md, or who haven't heard of the guide before. "About This
Guide" is still useful, but doesn't need to be the very first page.
