Update the balrog frontend to use Mozilla Protocol

[gabrielBusta]

The shipit frontend was updated to use the Mozilla Protocol design system with mozilla-releng/shipit#1339

We could do the same with the balrog ui.

Hey @gabrielBusta , since I am done with the docker compose issue, should I work on this issue or do you want me to work on some other issue?

[mundume]

@godplayer56 we are letting applicants work on whatever issues are available, and not worry about being assigned to things (in part because there's more contributors than issues.) The experience is valuable to everyone (even if an applicant's pull-request is not the one that ends up merged.)
