docs/concept: page-level additions to section TOC

This changes some pages' visibility inside the concept guide section's
TOC. This is done to work better with a parallel CL's addition of a
specific FAQ (symlinks) which makes sense to expose via the left-hand
nav TOC.

/docs/concept/faq/:
- include in parent section's left-hand nav TOC, placed at the bottom.
- include some on-page text introducing the list of FAQs, as the FAQ
  index will now be reachable from the left-hand nav.
- remove "(With Answers)" from section title, as it muddies this section
  and the parent section's left-hand nav TOCs.

/docs/concept/faq/*/:
- include in FAQ's section's left-hand nav TOC.

/docs/concept/modules/:
- add a weight to fix the page's position near the top of the parent
  section's left-hand nav TOC.
