Dbudzinski/new build

[dbudzins]

Description

To keep sync with partner and industry trends, we want to migrate off of snowpack and to vite. This PR does just that. Most of the changes are small 1-1 migrations (changing the build constant naming, updating the snapshots with the Vite header, updating test helpers from jest to vitest, etc.)

As mentioned above, I also migrated from jest to vitest. Jest doesn't work nicely with the vite build pipeline, and would require workarounds and a secondary test-only build setup, while vitest, though relatively new, works nicely with vite out of the box.

This PR solves #36.

Nice one! I also hope to spend some time today or tomorrow to pull the branch and to test the updated build / dev process.

Thanks for fixes! I also highlighted some issues with dependencies. It seems that we can get rid of async, jake and minimist, c8(?).
