[FEAT] Only display the relevant root package tree in the sidebar of a type page

Feature Name

The Desired Behavior

Only display a type's root package tree

i.e. If a user is on /docs/api/auth/testing/MockAccountRegistration, the sidebar should only display @daffodil/auth information instead of every API reference.

This is to reduce overcrowding of the sidebar.

Your Use Case

I don't think this is the correct thing to do. Instead, I think we should implement some kind of "child panes" for the package list sidebar like angular.dev does.

Okay, let me play around with designs.
