Fix firewall config to accept HTTP connections #279
Description
At the moment, connections to http://google.codecity.world, http://google.codecity.academy and http://google.codecity.games redirect to https://google.codecity.games, but https://google.codecity.academy and https://google.codecity.games do not. (That is: redirects from HTTP -> HTTPS canonicalise, but no redirect or canonicalisation is done for already-HTTPS connections.)
All connections should redirect to HTTPS to the server's canonical name.
