[next] Style the newly added About page

[chrispinkney]

What would you like to be added:
The about page desperately needs some styling as right now it's just displaying a markdown page.

Since we're not using a pagebase anymore styling it might end up being tricky, and I imagine prettier will end up being a pain and might need to be modified but we'll see.

I'd also like to incorporate the other docs found in the docs folder somehow, but I'll probably leave that for 1.7 (Sneak peek: I'd like to dynamically generate URLs for each document and style them accordingly)

Why would you like this to be added:
Nobody wants to see a boring about page.
