Docs: Specify correct port number values

[osg-grafana]

Feedback came in that I paraphrased somewhat, "At https://grafana.com/docs/mimir/latest/operators-guide/get-started/, if I just run docker run --rm --name=grafana --network=host grafana/grafana, there's no Grafana service available on port 3000 as specified later in the tutorial. I had to use -p 3000:3000:

docker run --rm --name=grafana -p 3000:3000 grafana/grafana

The problematic section: https://grafana.com/docs/mimir/latest/operators-guide/get-started/#query-data-in-grafana"

You are right, actually the Helm chart getting started guide did get this right: see https://grafana.com/docs/helm-charts/mimir-distributed/v4.1.0/get-started-helm-charts/#query-metrics-in-grafana
