Tradfri 1924G9 - support color and color temperature - bump herdsman converters

[jokakilla]

Hi,
thanks for the great work. In general the nodes are working very fine for me.

But I have some trouble with the Ikea Tradfri LED1924G9 which support setting color (color_xy) and color_temp.
https://www.zigbee2mqtt.io/devices/LED1924G9.html

When I try to set one of these values it always prints out that there is no converter available for that device type.

I guess bumping zigbee-herdsman-converters to the latest version could possibly fix that. I could manually change the devices.js of the herdsman-converters locally so color_temp is working. But probably having manual changes on my local installation is not a good idea.

I'm not sure if the dependency can simply be bumped to the latest version or if this could have bad side-effects. If you find time it would be great if you could have a look at that topic.
