dnsConfig are ignored for Windows pods

[orest-gulman]

I'm running EKS K8S 1.30 with EC2 Windows workers nodes only, coredns runing on fargate
There is an issue with dnsConfig that are ignored for Windows pods:

    spec:
      dnsPolicy: "None"
      dnsConfig:
        nameservers:
          - 192.168.1.100
        searches:
          - custom.domain

C:\app>ipconfig /all

Expected to happen:
