Light sensor is not detected on Gree Clivia

[fstancu]

Describe the bug

I am using the custom Gree Climate integration with a Gree Clivia air conditioner (GWH12AUCXD-K6DNA1C). Everything seems to work well, except the light sensor is never detected by the integration and therefore the light sensor switch is always shown as unavailable in Home Assistant.
Independent of the custom integration, the light sensor is properly working when activated using the AC remote control.

Also, the patch below, which skips the real detection of the light sensor, results with the light sensor switch available and properly working: on line 509 of climate.py, "if light_sensor:" is replaced with "if True:".

Enabling the debugging log for the integration produces the related log entries below:

To Reproduce
Steps to reproduce the behavior:

1. Install or reload the HA integration
2. Check the state of entity switch.gree_clivia_light_sensor
3. State is "Unavailable"

Expected behavior
Entity switch.gree_clivia_light_sensor is available after integration installation / reload.
