Provide a way to show the URL of a plugin source

[marckhouzam]

Describe the feature request

Currently there is no user-friendly way to see the URI of a plugin source. One had to look at the configuration (tanzu config get) and look for the URI in the yaml output.

I suggest that tanzu plugin source list provide that information either by default or when specifying a flag of some sort (.e.g., --verbose or --details)

Describe alternative(s) you've considered

Let the user look at the configuration, which is akward and non-intuitive.
