fix: Distance unit fixed

[Bubo08]

Should fix the kia_uvo problem: Not valid unit for device class distance #812

This should match the property approach of the rest of the file with a setter. On my phone so hard to link to an example but I can later.

Here is an example of unit being used.

Values being stored here:

hyundai_kia_connect_api/hyundai_kia_connect_api/Vehicle.py

Lines 143 to 145 in 2ca8b23

	_next_service_distance: float = None
	_next_service_distance_value: float = None
	_next_service_distance_unit: str = None

and setter getter:

hyundai_kia_connect_api/hyundai_kia_connect_api/Vehicle.py

Lines 258 to 266 in 2ca8b23

	@property
	def next_service_distance(self):
	return self._next_service_distance
	@next_service_distance.setter
	def next_service_distance(self, value):
	self._next_service_distance_value = value[0]
	self._next_service_distance_unit = value[1]
	self._next_service_distance = value[0]

Plus from the EU API this must be set correctly.

Marking as requested changes per above.

I took the following code as template as the odometer is not throwing this kind of error:

@property
def odometer(self):
    return self._odometer

@property
def odometer_unit(self):
    return self._odometer_unit

@odometer.setter
def odometer(self, value):
    float_value = get_float(value[0])
    self._odometer_value = float_value
    self._odometer_unit = value[1]
    self._odometer = float_value

Therefore I thought the unit setter function is missing and I added them. Why do you think this is not correct?

[cdnninja]

Oops you are correct. The rest was in before this PR.
