UPSTREAM: 1981: Backporting NetworkPolicy support for OLM bundles

This is a hack to backport "NetworkPolicy object kind in bundles" support from
operator-framework/operator-registry#1675
The feature was introduced in OCP 4.20 with a operator-registry bump to v1.55.0.
Ref:
1. operator-registry v1.55.0 release: https://github.com/operator-framework/operator-registry/releases/tag/v1.55.0
2. operator-registry bump in OCP 4.20: operator-framework/operator-controller#1981
Because the upstream PR is not being backported in operator-registry to older tags (with new z stream releases),
this achieves a downstream-only backport for this feature.
