docs:monitor: Fill in num_sensors_nonfunc_for_fan_nonfunc details

The `num_sensors_nonfunc_for_fan_nonfunc` attribute contains the number
of sensors that must be nonfunctional before the fan containing those
sensors are nonfunctional. This defaults to 0, meaning that the fan
enclosure's functional state will not be updated based on the functional
state of its sensors.
