Color_temp_kelvin should be adjustable via UI in the automation editor

[alexsaas]

Since Core 2025.1.XX If you have existing automations with color_temp or kelvin, warning messages like following will appear in the log:

Got color_temp argument in turn_on service, which is deprecated and will break in Home Assistant 2026.1, please use color_temp_kelvin argument

Unfortunately, it is currently not possible to set color_temp_kelvin in the automation editor UI, you have to switch to YAML for that.
