Round precipitation forecast to 1 decimal place (#15759)

Browse Source 
The OWM returns precipitation forecast values as they are submitted to their network. It can lead to values like `0.0025000000000004 mm` which does not make sense and messes up the display card. This PR rounds the value to 1 decimal place.
