Redirects git clones for core dependencies to the local repository for
both performance (avoiding unnecessary cloning) and correctness
(testing HEAD of everything).

+# This serves two purposes:
+# 1. Performance: Avoids repeated 100MB+ downloads of the monorepo for each dependency.
+# 2. Correctness: Ensures that changes in core packages (like google-api-core) are
+#    tested against downstream packages in the same Pull Request.
