Document config requirement for monitoring on imported AKS clusters

[catherineluse]

The context of this issue is that it was originally reported as a bug (rancher/dashboard#4658) in monitoring V1. In order for monitoring to work on imported AKS clusters, exporter-kubelets.https had to be set to true in the Helm chart values. I think that that kind of requirement is better addressed in documentation than in a UI change because when the UI injects certain values, it can lead to version incompatibility issues with the chart.

However, I just searched the monitoring helm chart values (https://github.com/rancher/charts/blob/dev-v2.7/charts/rancher-monitoring/100.0.0%2Bup16.6.0/values.yaml) and I didn't immediately see the same config option available for RKE2.

Someone should ask Team 3 the question: for V2 monitoring on imported AKS clusters, does it require the V2 equivalent of exporter-kubelets.https set to true? If so, I would suggest documenting it in the Rancher docs about monitoring and in the monitoring helm chart README.

The monitoring v2 chart has different values than V1. For V2, it looks to me like the equivalent value is kubelet.serviceMonitor.https and it is set to true by default. There is no cluster-specific kubelet section (rke2Kubelet, rkeKubelet or so on), so there should not be anything to configure.
