Add Air Humidifier CB (zhimi.humidifier.cb1) (#11327)

Since version 0.4.6, python-miio library support Air Humidifier CB (zhimi.humidifier.cb1), see release notes here: https://github.com/rytilahti/python-miio/releases/tag/0.4.6 and PR here: https://github.com/rytilahti/python-miio/pull/493/files. I've tested it on my setup with Home Assistant 0.102.1 and it works fine (I see the following attributes: https://www.screencast.com/t/jEg815pD), however, that model of Air Humidifier was not mentioned in the docs, so I added it.
