Knowledge base home page

[phitoduck]

This is the beginning of a version-controlled rewrite using sphinx of the original knowledge base site on notion: https://quickest-trail-808.notion.site/Rootski-Knowledge-Base-49bb8843b6424ada9f49c22151014cfc

I wrote a home page for docs.rootski.io and made several small improvements. You can visit the version of the docs built by this PR using the link further down in this PR conversation :D

1. the browser tab
   • added 📚 favicon
   • set title to "Knowledge Base"
2. added a small "pencil" icon to each page that lets you edit each docs page on GitHub; unfortunately, you have to enable "ReadTheDocs" mode for the pencil to appear, so I added a JS file that deletes a RTD menu that pops up when you open the site.
3. added a CSS file that adds a ↩️ icon to every "external" link so that users know which links take them off of the docs site (thank you FastAPI docs for the inspiration for this!)
4. created an rst/ folder where we will place all of our articles and other site content
5. added font-awesome CSS files to render
   • the LinkedIn, github, YouTube, and slack icons in the site footer
   • the "Helpful Links" section in the docs.rootski.io homepage
6. Added profile pictures of contributors to the docs.rootski.io homepage by creating a new CONTRIBUTORS.md file and registered it with the all-contributors CLI.
7. Achieved (6) and made it easier to credit future contributors by adding makefile targets to work with the all-contributors CLI.
