Feat: Resources as HTML

[angela-tran]

Closes #267

This PR adds support for hosting Resource pages as HTML.

To create the resource layout, I just copy-and-pasted from the press layout, and then I removed some things that don't apply to Resources. I referenced the resource from #266 to see what doesn't apply.

For testing purposes, I made a file at src/_resources/test.md with these contents:

1. apples
1. bananas

and here's what it looks like:

Here is what the link to that HTML resource on the Resources page looks like:
