Document what ports are scraped by default in k8s example

The Kubernetes pod SD creates a target for each declared port, as documented:

https://prometheus.io/docs/operating/configuration/#pod

> The pod role discovers all pods and exposes their containers as targets. For
> each declared port of a container, a single target is generated. If a
> container has no specified ports, a port-free target per container is created
> for manually adding a port via relabeling.

This results in the default port being the declared port, or no port if none are
declared.
