🐛 fix warning about invalid suggested_unit_of_measurement

Some walkingpad sensors are generating warnings in the logs:

>  <class 'custom_components.king_smith.sensor.WalkingPadSensor'> sets
>  an invalid suggested_unit_of_measurement. Please create a bug
>  report at https://github.com/madmatah/hass-walkingpad/issues. This
>  warning will become an error in Home Assistant Core 2024.5

Since the specified suggested_unit_of_measurements specified in the
sensors definition do not differ from their
native_unit_of_measurements, I don't think that they are very useful.
So I removed them.
