Android sound notification. Default is now "doorbell"

[naturelabsar]

Need to be fixed the documentation.

In Android: sound: "default" is not default sound anymore. This case trigger to get ringtones (long sounds, for phone calls for example) instead notifications sounds, because of that the channel get "none" sound (everything can be verified in settings of android devices)

If sound: "doorbell" is setted you can really get "default" notification sound.

Please change documentation that "doorbell" is the new "default" notification sound

Thanks!
