Daniel Sobral's FAQ Corner, front page

[heathermiller]

Need to make a place for Daniel to add his FAQs to.

The geoal is to have them have their own subsection on the doc-site (assuming FAQ pages keep being added). But it'd also be nice to give them a place on the front page- for example, two or three could randomly be chosen and displayed.

FAQs are still inside Tutorials (as discussed in #6), and are still hard to find. I almost failed preparing #270 just because I couldn't find either FAQs or a sitemap.

https://docs.scala-lang.org/tutorials/FAQ/index.html exists and is prominently linked from the front page

(but the content is very stale...)
