Use unminified css and remove minified

[NickSto]

Fixes #60

Almost! This looks good in desktop mode but I do notice that in mobile mode the responsiveness is broken. Let's fix that before merging this

[sheldon-b]

note on how I tested it: the CI step for deploy/netlify links to a preview environment where this PR gets deployed to. Then I opened up the production website in another tab and compared them across all of the pages

[NickSto]

I don't see the mobile issue anymore, nor the different font size I noticed previously 🤔

I've checked in the local version and the Netlify preview in Firefox and Chrome.

If someone else can verify, I think this is ready to merge.

[sheldon-b]

@NickSto I still see the logo being broken in the netlify preview deployment. I did merge your other PR though

[NickSto]

@sheldon-b Oh this PR doesn't cover the broken logo. I separated the issues, so this only changes us to be using the correct css file.

[sheldon-b]

Got it. Do we need to migrate your fix from the logo-fixing PR into this PR before merging then, to make sure we don't break the logo again?

[NickSto]

@sheldon-b That PR is entirely decoupled from this one. I moved the changes to main.css, and this only affects the uswds css files. So you should be able to merge this w/o affecting the logo.
