setup routing and empty state query building pages

[fzhao99]

PULL REQUEST

Summary

First piece of the query building frontend work that sets up the empty state page and routing. Turning off the navigational link in production, but accessible locally via the gear icon once signed in / in demo. Can also navigate to the empty state page at /queryBuilding

For design:

Once you navigate to the query building page, do a generic sweep to make sure the empty state page matches designs - spacing / sizing / color of the empty state box pages

Did also tokenize the font styles for h1/h2's (to Merriweather), body (to Public Sans Web), and the site title / mono (to Consolas), so do a step-through of the pages in the rest of the app to ensure those fonts are applied correctly.

Fixes #74 and #73

Additional Information

• Tokenized the fonts of the header files to use the new text styles that we're using across the application using the USWDS stylings. Updated heading, body, site title to match
• Tokenized some colors for use in a few places with the changes to the spacing
• Moved the SelectQuery.tsx file out of the root query directory
• Moved the stepIndicator folder into the `components directory
• Collapsed two utils files into one
• Deleted some unnecessary stylings

QUE-30 Set up routing to get to query building

looks good! just to note, for docker, when I tried to follow the logic to sign-in, my little dropdown only had the sign out; I could only get the My queries button on npm run dev so we might need another way for @mikang to test since that workflow uses Docker. Or commenting out !isProduction until we merge so that docker can be used to test the workflow.

Ahh yes good point! Realized the docker setups gauge those production flags differently.

The page is accessible via URL at /queryBuilding so we can do that too.

LGTM 🚀 . Couple comments below but nothing is blocking.
