Improve ThemeService saving

[tinodin]

Currently ThemeService saves its config in Path.Combine(PathHelper.GetAppDataFolderPath(), ProcessInfoHelper.ProductNameAndVersion, "CoreAppConfigV9.2.0.json") which can fill up the LocalState folder with many folders and files with every version update of the app. Also it doesn't seem practical to save two properties inside of a .json file and the name CoreAppConfigV9.2.0.json doesn't make sense since it seems to append an old version of DevWinUI.

Could we use ApplicationData.Current.LocalSettings?

Hi @tinodin
i always forget to update version, sorry about it.😅
Currently, ApplicationData.Current can only be used for packaged applications. Unpackaged apps will encounter exceptions due to missing Package Identity.

The ApplicationData.GetForUnpackaged() method is expected to be available soon, which will allow us to fully transition. Until then, we’ll continue using our internal saving mechanism.

@ghost1372 Until then can we maybe reuse the same folder without the app version and not create a new one with every new version of the app?
