Add support for NodeLocal DNSCache (169.254.20.10) in the DNS egress network policy. This fixes DNS resolution issues on GKE Autopilot and other Kubernetes environments that use node-local DNS caching. Changes: - Rename policy from allow-egress-to-kube-dns to allow-egress-to-dns - Add NodeLocal DNSCache IP (169.254.20.10/32) as allowed DNS target - Add migration logic to clean up old policy name - Add Troubleshooting section to README with DNS resolution guidance Fixes restatedev#54

The previous DNS network policy only allowed traffic to
kube-dnspods via label selector. On GKE Autopilot (and other clusters with NodeLocal DNSCache enabled), DNS queries go to169.254.20.10instead, which was blocked.Testing
