Description of problem:
https://bugzilla.redhat.com/show_bug.cgi?id=1931281
prometheus version had been bumped to 2.26.0, but the prometheus pods' label is still app.kubernetes.io/version=2.24.0, we also need to update other resources, example: prometheuses/prometheusrules/servicemonitors/clusterrolebindings/clusterroles
