ci/gke: End quarantine for Hubble tests
ci/gke: End quarantine for Hubble tests

Previously, these tests were quarantined because the unmanaged Hubble
Relay pods were not able to establish connectivity to the nodes. This
has been fixed, therefore we can remove the quarantine for these tests.

Fixes: #12452
