Docs: remove link to Zigbee2MQTT page about tuya debugger.

The debugger only provides links between id and name. It was needed using
the older API Explorer method that only returned dps that fitted the standard
data model to at least get names for other dps that appeared in the log.

The QueryThingsDataModel that is now recommended does not seem to miss any
dps, so the debugger instructions are just a distraction, and have led
users to assume it is an alternative to API Explorer method, when it is not
providing detailed info about the dps, only names.

 If your device is not listed, you can find the information required to add a configuration for it in the following locations:
 
-1. When attempting to add the device, if it is not supported, you will either get a message saying the device cannot be recognised at all, or you will be offered a list of devices (maybe a list of length 1) that are partial matches, often simple switch is among them.  You can cancel the process at this point, and look in the Home Assistant log - there should be a message there containing the current data points (dps) returned by the device.

 2. If you have signed up for [iot.tuya.com](https://iot.tuya.com/) to get your local key, you should also have access to the API Explorer under "Cloud". Under "Device Control" there is a function called "Query Things Data Model", which returns the dp_id in addition to range information that is needed for integer and enum data types.
-3. By following the method described at the link below, you can find information for all the data points supported by your device, including those not listed by the API explorer method above and those that are only returned under specific conditions. Ignore the requirement for a Tuya Zigbee gateway, that is for Zigbee devices, and this integration does not currently support devices connected via a gateway, but the non-Zigbee/gateway specific parts of the procedure apply also to WiFi devices.
