Include from_pg_version in postgres-logs artifact name

The upgrade matrix runs multiple from-version pairs (16->18, 17->18)
that share a target pg_version, so the postgres-logs artifact name
still collided after the worker_id fix.  Append -from<N> when the
run-test action has a from_pg_version input.
