Revert escaped underscore changes in thermostat URLs

The \_  escaping is intentional GitBook markdown to prevent italic
rendering. The validator should handle this, not the content.

 You can configure Seam to emit a [`thermostat.temperature_threshold_exceeded` event](https://docs.seam.co/latest/api/events/) if a thermostat reports a temperature outside a specific threshold range. This capability helps you to monitor your thermostats proactively, alerting you to potential HVAC system misuse or malfunctioning.

 When the thermostat reports a temperature outside the threshold range, Seam also adds a warning on the thermostat. You can use the [`/devices/get`](https://docs.seam.co/latest/api/devices/get) endpoint to get the thermostat and then inspect its `device.warnings` property.

 ## Change a Temperature Threshold
 
-To change the temperature threshold range for a thermostat, issue a new [`/thermostats/set_temperature_threshold`](https://docs.seam.co/latest/api/thermostats/set_temperature_threshold) request. The new threshold values replace the previous ones.
