Use non-canonical repo name in hub repo (#2491)

#2461 changed the rendering of the hub repo to use canonical repository
names, but incorrectly. Doing so wasn't necessary - instead we just need
to do the resolution of the non-canonical label from the perspective of
the hub repo rather than the consumer by using the `Label` constructor.

Fixes #2483
