Add --test-against localhost:8080 to proxymock replay commands

The pulled traffic was recorded from Kubernetes where the service was
called outerspace-server:8080. When replaying in CI, we need to
redirect these requests to localhost:8080 where the service actually
runs.

This fixes the "generator run failed: readiness checks: tcp probe
against outerspace-server:8080: unable to connect" error.
