[Feature] Upgrade the FAQ page

[3vorp]

Is your feature request related to a problem?

Right now, it's just one long list, which sucks for basically everything.

Describe the feature you'd like

Split up the FAQ items into different sections—I was thinking of having three different categories: for users, for contributors, and for creators (and organizing them as cards using the examples below). For each category, we could probably adopt an accordion layout as well to save on vertical space, and open/anchor the correct one depending on where the search takes you (similar to how the downloads page anchors you based on the hash).

Additionally, improve the search bar interface to show the questions ahead of time using Vuetify's autocomplete features.

Notes

This can leverage Nuxt's dynamic routing to do some interesting stuff once the rewrite is out.

Also possibly rename the FAQ stuff to like a separate "support" area of the site.
