docs: repin the commit-distance figures that were measured to the old tip

The counts for how far the earlier baselines' citations had drifted were taken to
`d615b75` and read 411 and 435. Measured to `048e28a` they are 416 and 440, and the
two spans are now named separately rather than averaged into one number, since the
two documents' citations have different origins.
