Allow None on Renault binary sensors

[epenet]

Breaking change

Previously, Renault binary_sensor entities could have the state on or off, and in case the endpoint was unreachable: unavailable. However, it wasn't able to have the unknown state, which has been added.

So, a binary_sensor entity can now have the on, off, unavailable, or unknown state.

You might need to adapt your automations or scripts to take this new unknown state into account.

Proposed change

As spotted in #65993, and as follow-up to #60193, allow None on Renault binary sensors
