Enable support for HassClimateSetTemperature intent

[mib1185]

• needs: Add HassClimateSetTemperature intent core#134316

At the moment the action climate.set_temperature does not support the temperature_unit argument -> an architectural discussion has been started, but it most properly results in a more broader and generic solution, than just add the argument to this single action call.

So even the intent supports the temperature_unit argument, the underlying action call doesn't.
Can we keep temperature_unit argument in the existing sentences or should we remove it for now?

I think this is discussion material, but here's my 2c until you open one: we should not remove the optional temperature unit, but we should add context to the intent. Something like:

# sentences/en/_common.yaml
expansion_rules:
  degrees_c: ([ ]°[[ ](c[elsius])])|( degrees c[elsius])
  degrees_c: ([ ]°[[ ](f[ahrenheit])])|( degrees f[ahrenheit])
  temperature_c: "{temperature}[<degrees_c>]"
  temperature_f: "{temperature}[<degrees_f>]"

# sentences/en/climate_HassClimateSetTemperature.yaml
intents:
  HassClimateSetTemperature:
    data:
      - sentences:
          - "(<numeric_value_set>|adjust) <temp> [in <area>] to <temperature_c>"
          - "(<numeric_value_set>|adjust) <area> <temp> to <temperature_c>"
        requires_context:
          temperature_unit: "celsius"
      - sentences:
          - "(<numeric_value_set>|adjust) <temp> [in <area>] to <temperature_f>"
          - "(<numeric_value_set>|adjust) <area> <temp> to <temperature_f>"
        requires_context:
          temperature_unit: "fahrenheit"

Then the conversation agent would include the system temperature unit in the context.
