Use metric units internally in all weatherproviders (#2849)

So finally I think this refactorin is ready to be reviewed :-) DONE: - [x] Removed all conversion functions for wind and temperature from specific weatherproviders - [x] Use internally only metric units: celsius for temperature, meters per seconds for wind - [x] Convert temp and wind into the configured units when displaying data on the UI - [x] look how beaufort calculation uses metrics, added knots as new windunit - [x] add more e2e tests Checked providers: - [x] Darksky - [x] EnvCanada - [x] OpenWeatherMap - [x] SMHI provider - [x] UK Met Office - [x] UK Met Office DataHub - [x] WeatherBit - [x] WeatherFlow - [x] WeatherGov TODO in different tickets: - check weatherproviders for usage of weatherEndpoint (as seen in https://github.com/MichMich/MagicMirror-Documentation/issues/131) -> see #2926 - cleanup precipations -> #2953 Co-authored-by: veeck <michael@veeck.de>
