View Documentation button on Cluster page goes to wrong docs

Summary

The View Documentation button on the Cluster Pages takes you to "Monitoring GitLab with Prometheus" .

This probably isn't relevant to the user as they are more than likely trying to monitor their own app & not a deployment of Gitlab.

Steps to reproduce

1. Add a Kubernetes cluster to your project
2. Visit the Cluster page in Operations > Kubernetes >
3. While the data is loading, click the View Documentation button

Example Project

https://gitlab.com/seanarnold/autodevops-rails-test (I can add you as a Maintainer).

What is the current bug behavior?

Link goes to somewhere irrelevant.

What is the expected correct behavior?

As a user, I want to be sent to some helpful docs.
