Pyrra's Prometheus links are broken

[ArthurSens]

Currently, if we click on Pyrra's Prometheus links, we're redirected to the same URL pyrra uses to communicate with prometheus, which is the Kubernetes internal DNS. Such DNS is not accessible from our browser, so the experience is not great.

We can set the PrometheusExternalURL arg to victoriametrics, but victoriametrics also doesn't have a UI.

What we could do is:

• Deploy VMUI and make it available to the internet, then set the externalURL argument to VMUI

or

• Suggest and contribute to Pyrra, if maintainers agree, that Pyrra's UI could also redirect such links to Grafana instead of Prometheus.
