Reapply "Make some of the bundle commands Sorbet typed: true"

- This reverts commit 68dbf12220f9a52ddf5ca5eb3aa1b356aa42da3a that was
  a revert of commit 68596ec720a50f44ae9c30c5806aa7f2d4bcc96f because I
  put the RBI file in the wrong place and Tapioca got rid of it, causing
  this week's release to be blocked.
