Fix binary_sensor.template example (#2877)

Browse Source 
The binary_sensor.template was return states of "On" and "Off",
however that doesn't seem to work in 0.47. You need True / False,
which makes sense, given that's what the single line evals are going
to return. Update the existing example, and add another one about
computing composite occupancy from device tracker and motion sensors.

### {% linkable_title Combining multiple sensors, and using entity_id: %}
This example combines multiple CO sensors into a single overall status. It also shows how to use `entity_id`
This example combines multiple CO sensors into a single overall
status. When using templates with binary sensors, you need to return
`True` or `False` explicitly. `entity_id` is used to limit which
sensors are being monitored to update the state, making computing this
sensor far more efficient.

### {% linkable_title Is anyone home? %}
This example is determining if anyone is home based on the combination
of device tracking and motion sensors. It's extremely useful if you
have kids / baby sitter / grand parrents who might still be in your
house that aren't represented by a trackable device in home
assistant. This is providing a composite of wifi based device tracking
and z-wave multisensor presence sensors.
