Fix Tuya cover state being interpreted as position

[DomiStyle]

Fixes Koenkk/zigbee2mqtt#6601

[DomiStyle]

Since state and coverChange were previously used to determine the running attribute this will break the running attribute on older models like mine. Since it doesn't really serve a purpose it shouldn't be an issue.

Newer models will report the running attribute via coverPosition.

Hi, my setup is the following: Debian + Home Assistant (supervised) incl. AddOns (Z2MQTT + MQTT broker).

I've used the auto-discovery function and was able tu successfully implement this device. However, I cannot see any position data at all, nor am I able to adjust this value. When I try to move the position slider in my Z2MQTT add-on nothing happens.

At least I can close and fully open it when I press the up and down arrows.

Is it this based on the bug described here or do I have to configure it manually to be be able to see and set position data?
