title: update prometheus charts from prometheus-operator to kube-prometheus-stack
body: <p>Recently <a href="https://github.com/helm/charts/tree/b9278fa98cef543f5473eb55160eaf45833bc74e/stable/prometheus-operator" rel="nofollow noreferrer">prometheus-operator</a> chart is deprecated and the chart has been renamed <a href="https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack#configuration" rel="nofollow noreferrer">kube-prometheus-stack</a> to more clearly reflect that it installs the kube-prometheus project stack, within which Prometheus Operator is only one component.</p>
  <p>I checked both old and new chart and also I read all related documentation, but I couldn't find changes in the files(especially in <code>values.yaml</code>), could someone explain me to migrate from prometheus-operator to kube-prometheus-stack what I should do exactly?</p>
