transferToRemote RPC has misleading comments

[RonanMacF]

https://github.com/openconfig/gnoi/blob/main/file/file.proto#L36 mentions

  // TransferToRemote transfers the contents of a file from the target to a
  // specified remote location.

This makes sense.

https://github.com/openconfig/gnoi/blob/main/file/file.proto#L116 mentions

// A TransferToRemoteRequest specifies the local path to transfer to and the
// details on where to transfer the data from. The local_path must be an
// absolute path to the file.
message TransferToRemoteRequest {
  string local_path = 1;

  // Details to download the remote_file being requested to a remote location.
  gnoi.common.RemoteDownload remote_download = 2;
}

I don;t think this is right, this seems to be describing a transferFromRemote RPC which doesn't exist.
