documentation: fix rendering and internal references

This is mainly cleanup after switching from Github-flavoured Markdown
rendered by Github Pages, to standard Markdown rendered by MkDocs.

Changed:
- rephrase some section titles

Fixed:
- list rendering (items, sub-items))
- code rendering
- quotes
- dead links

Removed:
- extraneous navigational elements
