Merge #253: Add additional slash to show ReceivePayjoin cli docs

a6d22b9 doc(payjoin): add additional slash to show ReceivePayjoin cli docs (nymius)

Pull request description:

  ### Description

  A missing slash was preventing the `receive_payjoin` command from displaying its documentation string:

  ```bash
  Wallet operations.

  ...
    sync               Syncs with the chosen blockchain server
    broadcast          Broadcasts a transaction to the network. Takes either a raw transaction or a PSBT to extract
    receive_payjoin
    send_payjoin       Sends an original PSBT to a BIP 21 URI and broadcasts the returned Payjoin PSBT
    new_address        Get a new external address
  ...
  ```

  This change adds the additional slash to make a proper doc string, so clap displays it.
