Add air quality and environmental state roles

Sync lib/config_StateRoles.js with the current stateroles.md
definitions from ioBroker.docs. Adds new value.* roles for air
quality and environmental sensors (co, no, no2, o3, ch2o, pm1,
pm25, pm10, rn, tvoc, airquality, humidity.relative,
humidity.absolute) and defines type/read/write constraints for
value.temperature.dewpoint. No roles were removed.

+* (mcm1957) Added new state roles for air quality and environmental sensors (`value.co`, `value.no`, `value.no2`, `value.o3`, `value.ch2o`, `value.pm1`, `value.pm25`, `value.pm10`, `value.rn`, `value.tvoc`, `value.airquality`, `value.humidity.relative`, `value.humidity.absolute`) and defined type/read/write constraints for `value.temperature.dewpoint`.

 ### 5.20.8 (2026-08-09)
 
 * (mcm1957) Fixed source directory exclusion so multi-level paths (e.g. `src/lib/scripts`, `src/scripts`) are correctly skipped during code scanning, avoiding false positives such as `[S5051]`.
