Refactor faq

[versecafe]

This moves the FAQ from a huge stack of HTML/Astro syntax over to easy to edit MDX files with compile time checks making it far easier to add, remove, or adjust them as needed, a new FAQ is as simple as

src/content/faq/[name]

---
question: Why use Astro
---

We moved over from HTML/CSS to Astro to make site maintenance easier on the
team and make adding new content for updates, posts, newsletters, new sponsors,
and more easier.

Note that by using MDX instead of MD it gives support for custom formatting if ever needed, some places had <br /> tags injected to make spacing look nicer, or may in the future need a <img> tag or custom tailwind for a gradient word.

The move away from a single file for both donate and faq is nice, but the separate files for each faq entry means that the faq entries are arbitrarily shuffled. We organized them in a specific order for a reason, intended to be read in that order.

So either slapping them all into one mdx file, or some way to describe an order for them needs to happen before this is ready to go.
