Merge rust-bitcoin#5135: chore: fix path to the wrapper

60ee4ca chore: fix path to the wrapper (phrwlk)

Pull request description:

  The comments contain an incorrect path to the wrapper.
  In fact, the bridge module is not public (mod bridge;), and the FromStd type is re-exported at the top level. Correct ways to use it: io::FromStd (as in the code on L89) or, if connecting the crate without an alias, bitcoin_io::FromStd.
