[Bug] Enabling core networking addons to be configured for clusters with a mix of EKS Auto Mode and Hybrid nodes compute

[RobertNorthard]

What were you trying to accomplish?

Run eksctl create cluster with a cluster.yaml file that has EKS Auto Mode and Hybrid nodes configured along with the required addons (CoreDNS and kube-proxy). I would expect to be able to configure kube-proxy and coredns in a cluster that has both EKS Auto Mode and Hybrid nodes compute.

What happened?

eksctl presented the following error:

Error: core networking addons are not required on a cluster using Auto Mode; if you still wish to create them, use `eksctl create addon` post cluster creation

How to reproduce it?

1. Create the following cluster.yaml

apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig
metadata:
  name: cluster
  region: us-west-2
  version: "1.32"

addonsConfig:
  disableDefaultAddons: true

autoModeConfig:
  enabled: true
  nodePools: ["general-purpose", "system"]

remoteNetworkConfig:
  iam:
    provider: ssm
  remoteNodeNetworks:
  - cidrs: ["172.18.0.0/16"]
  remotePodNetworks:
  - cidrs: ["172.17.0.0/16"]

addons:
  - name: kube-proxy
  - name: coredns

2. Run eksctl create cluster -f cluster.yaml and get the following message:
