feat: openfoodfacts#960 - changed the attribute/importance preference…

… display.

Impacted files:
* `attribute_button.dart`: changed the whole display.
* `design_constants.dart`: added a constant for the default icon size.
* `product_preferences.dart`: added the downgrading of "very important" to "important".
* `pubspec.lock`: wtf
