Subject: [PATCH 1/1] Switch to Furo (#2793)

- Add Furo dependency to docs/requirements.txt
- Drop a fair bit of theme configuration
- Fix the toctree declarations in index.rst
- Move stuff around as Furo isn't 100% compatible with Alabaster

Furo was chosen as it provides excellent mobile support, user
controllable light/dark theming, and is overall easier to read

 By using *Black*, you agree to cede control over minutiae of
 hand-formatting. In return, *Black* gives you speed, determinism, and
