feat(plugin-nested-docs): pass collection config as an arg to generateURL and generateLabel (#14086)

Closes #10378

We now pass `collection` containing the current collection's config into
the `generateURL` and `generateLabel` as a third parameter.

In the future we should change this into an object so we can more easily
insert new params.
