Describe the bug:

This bug is covered by a bigger bug: rancher/rke2#4772

When we are in dualStack mode, metrics and kube-dns services are all SingleStack. We can manually change that but I think it makes more sense if both were dualStack automatically

Steps To Reproduce:

• Installed K3s:

Deploy k3s in dualStack mode and check the ipFamilyPolicy: in metrics-server and kube-dns services

Expected behavior:

Services have an ipv4 and an ipv6 address when deployed in dualStack mode

Actual behavior:

Services only have on IP address when deployed in dualStack mode
