Configuration creates two security groups with `kubernetes.io/cluster/k8s-gpu-cluster` tag

I followed the guides to launch a k8s cluster with a p4de instance and I think the default security groups it created had two groups with the `kubernetes.io/cluster/k8s-gpu-cluster` tag included. When trying to later create an ingress load balancer using the aws load balancer controller, the loadbalancer failed to configure everything.

This matches [this error report](https://github.com/kubernetes-sigs/aws-load-balancer-controller/issues/1897) and deleting the tag in one security group resolved the issue.

It'd be very helpful to figure out where this double tagging is happening and add a fix so that eks clusters are well configured for load balancers.
