docs: // ListParticipation returns the total commit counts for the 'owner'
  // and total commit counts in 'all'. 'all' is everyone combined,
  // including the 'owner' in the last 52 weeks. If you’d like to get
  // the commit counts for non-owners, you can subtract 'all' from 'owner'.
  //
  // The array order is oldest week (index 0) to most recent week.
  //
  // If this is the first time these statistics are requested for the given
  // repository, this method will return an *AcceptedError and a status code of
  // 202. This is because this is the status that GitHub returns to signify that
  // it is now computing the requested statistics. A follow up request, after a
  // delay of a second or so, should result in a successful request.
