infrastructure: remove staging subdomain route53 zone

This caused a collision with an entry for 'staging' in the
main route53 zone that terraform did not catch and warn about.

The intent was to avoid pulling in the top level zone as its
managed by someone else, but since we ended up just creating
the DNS entry manually let's drop the subdomain zone.
