Fix support for airqualitymonitor running firmware v4+

[WeslyG]

New firmware versions (v4+) for cgllc.airmonitor.s1 respond only with ["ok"] when unsupported properties are requested.
This PR removes the battery prop from the query to make it work on devices running running firmware versions.

LGTM, thanks @WeslyG! 👍 I changed the description and the title, hopefully correctly, to make it more clear what was changed and why :-)

[WeslyG]

@rytilahti Thank you for accepting)

in which version of home assistant will the fix be released?

[rytilahti]

There is no formal release schedule, so it will be fixed at some point when I'll find some time to create a new release and the dependency gets bumped in homeassistant. The library is currently ongoing some larger changes and I'm busy with other responsibilities, so I'm not going to make any promises when that will happen.
