2023.9: forecast-related changes

[ildar170975]

2023.9 introduced changes related to forecast data.
Seems that the card need to be updated to support these changes.

@Yevgenium yes, if i understood correctly we now need to use the weather.get_forecast function: Link. As I am not a developer, I can't do the changes on my own and check them in :-(

@Yevgenium could you fix this issue as soon as possible, please?

So sad, that this great thing obviously is dead :-(
