Areas or cases that should be tested

Go to Explore > Cluster > Nodes:

• make sure we display the same external/internal ips that kubectl would return
• when multiple external/internal ips are available we display the "+{n} more" pill and it works as expected(like how it's been mentioned in the ticket under UI requirements)

The InternalExternalP formatter is also used in the cluster detail page; this PR has broken it such that it always shows - / Same as External

I think what needs to happen is for the updated getters to be added to cluster.x-k8s.io.machine model to support rke2/k3s clusters detail page. At a glace it looks like they'd be veeery similar to what you have in the node model already. I think the management.cattle.io.node model is only used for rke1 detail page so we should be ok to leave it alone, but worth double-checking that
