Updated Metallb 0.13.7 Configuration for K8s 1.25

In the new metallb first, we need to enable the ARP using the following command

kubectl get configmap kube-proxy -n kube-system -o yaml | \

sed -e "s/strictARP: false/strictARP: true/" | \

kubectl apply -f - -n kube-system

Then apply the new metal lb file. 

kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.13.7/config/manifests/metallb-native.yaml

Apply the following Yaml to mention the IP's which Metal LB can use.
