OCPBUGS-59570, OCPBUGS-59566: Move Network Policy manifests

The manifests are in the wrong place currently. This repository has
static manifests that get copied to the container image during build time,
from a static location (the `/manifests` folder). Moving over the
NetworkPolicy manifests to the right location so that they're actually
applied on cluster.
