Make smartthings use the right unit of measurement for illuminance sensors

[joostlek]

Proposed change

As described in #95170, the set native unit of measurement is set to lux, whilst it should be lx. The current Smart things code has support for changing the received unit into a HA unit.

unit = self._device.status.attributes[self._attribute].unit
return UNITS.get(unit, unit) if unit else self._default_unit

Since default unit it set on our side, the only way the integration returns lux is that the device is returning this. This PR translates lux into lx to fix the issue described.

Can not test this, but I am confident that this is the way to fix it.
