~whereswaldon/arbor-dev#171: 
Add summaries to documentation pages for OG previews

MkDocs supports "summaries" in the YAML frontmatter that provide OG description tags. Filling these in for all of our pages will improve SEO as well as simply making them look better when sharing on other platforms.

The format is…

---
title: Title of page here
summary: Longer description that provides more information about the page
