Add support for a 3-in-1 CO2 device (PV28-AW model) (#4460)

* Add support for a 3-in-1 CO2 device. The PV28-AW model. Recognized in Tuya as "CO2_DETECTOR" (all capital letters).

* Address feedback from pull request: Use homeassistant naming style and more specific classes where possible.

* fix (pv28aw_co2detector): rename file and drop name

- rename file to follow standard convention order
- drop the name from battery_charging sensor to allow translations to show

PR #4460
