Enable nginx service to use IPv4 and IPv6 on the cluster network.
Update overrides to compute `ipFamilies` from address pools and
set `ipFamilyPolicy: PreferDualStack`, prioritizing the cluster’s
primary pool.
Test Cases:
PASS: build-pkgs.
PASS: On an AIO-SX system with dual stack configured:
- Running `kubectl describe` for the nginx service pod should
return both IPv4 and IPv6 on the `IP Family Policy` section.
- Attaching to a running pod and performing a `nslookup` on
the nginx service name should return ips for both families.
