Add debugging steps for DiscoverEKS User Task issues (#50909)

This PR adds description to all known discover EKS issues.

It also adds URLs that the user can follow to fix or further debug the
issue.
The URLs are per-cluster, and they usually link to Amazon EKS Cluster
page or one of its sub pages.

+The process of automatically enrolling EKS Clusters into Teleport, starts by installing the [`teleport-kube-agent`](https://goteleport.com/docs/reference/helm-reference/teleport-kube-agent/) to the cluster.

+If the installation is successful, the EKS Cluster will appear in your Resources list.
+
+However, the following EKS Clusters did not automatically enrolled.
+This usually happens when the installation is taking too long or there was an error preventing the HELM chart installation.
