custom_components.smartthinq_sensors.light.LGELight does not set supported color modes, this will stop working

[SeanPM5]

Describe the bug When restarting Home Assistant, there is an error in the logs. which is related to the light entity from microwave.

Logger: homeassistant.components.light
Source: components/light/__init__.py:1267
integration: Light (documentation, issues)
First occurred: 12:42:36 AM (1 occurrences)
Last logged: 12:42:36 AM

None (<class 'custom_components.smartthinq_sensors.light.LGELight'>) does not set supported color modes, this will stop working in Home Assistant Core 2025.3, please create a bug report at https://github.com/ollo69/ha-smartthinq-sensors/issues

Here is a blog post on HA Developers site about change and link to developer docs for light color mode. It seems that it's now required to specify ColorMode.ONOFF in supported_color_modes instead of leaving it blank.

Note: There is also a ColorMode.BRIGHTNESS but I don't know if that fits since you have to change brightness via effect. So I think ColorMode.ONOFF is most accurate for the microwave light.

Below is screenshot and state of the light entity from my microwave.
