message: Allow the rustfmt step to fail
  The weekly openapi job can remove files when their surface shrinks
  leading to a broken pipeline. This allows that failing step to
  pass, which in turn pushes up a broken and unformatted PR in that case.
  Since we have to fix API breakages anyways, that is reasonable.
