Redirect an empty RDAP path to the /help response (#2722)

Browse Source 
The behavior when someone hits the plain RDAP base URL isn't specified
by the spec. Currently we just return a plain 404 which isn't
particularly nice or helpful -- so it would probably be nicer to just
redirect to the /help response instead.

tested on alpha,
https://pubapi-dot-domain-registry-alpha.appspot.com/rdap redirects to https://pubapi-dot-domain-registry-alpha.appspot.com/rdap/help
