Support documenting re-exported functions

[adamtheturtle]

I have a file example.bzl.

I want my users to load the rule foo from example.bzl - that is the interface I am promising.

foo is defined in other.bzl and exported from example.bzl as follows:

# example.bzl

load(":other.bzl", _foo = "foo")

foo = _foo

I expect to use autobazel-rule to document example.bzl:foo but this errors as the rule is not found.

Instead I have to document other.bzl:foo.
This is problematic as this is not the stable interface.
A title is rendered with other.bzl:foo in it.

My request is that this package is changed either to allow me to document example.bzl:foo, or to allow me to override the title given when I document other.bzl:foo.
