Docs should have the name of file to load to get each rule.

How do you know that you need to load @rules_pkg//pkg:zip.bzl to get pkg_zip?

Maybe fixed by #530.
But, perhaps we should fix it as part of #524

[aiuto]

#530 got the information there, but it looks ugly.
I think folding it into the renderer from #524 is a better idea.

• Can we automatically associate //pkg:tar.bzl with pkg_tar, even though the implementation is in pkg/private/tar? and wrapped in a macro?
• It would be nice if the private part did not have to know where the public part was, but I can forgo that.
• We should invent new syntax for this, so we can get a consistent rendering.
  perhaps @location("//pkg:tar.bzl")

Lowering to P2 because there is something, but ugly. This is also something that should be part of stardoc.

This is as done as we are likely to get for now. If stardoc every adds the capability, we can update to that.
