[x/go.dev] cmd/frontend: redirect /explore to discovery site

This adds an application for redirecting /explore requests to the
correct discovery site, depending on which domain is requested.

All static content should be served by appengine itself. The static
handler only is necessary for testing locally.

Fixes b/142726792
