bug: DigitalOutputChannel need the port to be instantiated as a tuple

[TheoLaudatQM]

@quam_dataclass class DigitalOutputChannel(QuamComponent): """QuAM component for a digital output channel (signal going out of the OPX)

Should be added to `Channel.digital_outputs` so that it's also added to the
respective element in the QUA config.

Args:
    opx_output (Tuple[str, int]): Channel output port from the OPX perspective,
        E.g. ("con1", 1)
    delay (int, optional): Delay in nanoseconds. An intrinsic negative delay of
        136 ns exists by default.
    buffer (int, optional): Digital pulses played to this element will be convolved
        with a digital pulse of value 1 with this length [ns].
    shareable (bool, optional): If True, the digital output can be shared with other
        QM instances. Default is False
    inverted (bool, optional): If True, the digital output is inverted.
        Default is False.

I believe this has been fixed with the introduction of ports, feel free to reopen if not fixed
