Typo on integraion/prometheus page

Is this a BUG REPORT or FEATURE REQUEST?

BUG REPORT

What happened:
The podMonitor example under the "Prometheus community version (helm) - kube-prometheus-stack with pod monitor" section will scrap the metric from all the pods which port is TCP and the pod with target label.

What you expected to happen:
It should only scrape the metric from the target pod by combining two array items under the podMetricsEndpoints into a single item.
