fix: remove undefined aws_eks_verify_cluster and aws_eks_get_cluster_info calls (#4398)

These functions were removed but their call sites in eks-helm.sh and
eks-operator.sh were not updated, causing "command not found" errors
in the eks-helm-nightly pipeline.

Backport of the fix from main (PR #3610) to release-1.9.
