Subject: [PATCH] Add references to the GitHub graph (#434)

This is a very simple extension of #431 to use the new reference
detection logic added in #429.

Test plan:
Inspect snapshot change for plausibility. Note that the snapshot adds
exactly 16 reference edges, which is the same as the number of
references in the reference snapshot test.
