⚡ improvement(index): make silentTranslationWarn work for dates and n…

…umbers too (#481) by @Raiondesu

Currently, the `silentTranslationWarn` flag only disables warnings for regular translations, which, I think, is not what people would expect from this option. Even when `silentTranslationWarn` is enabled - warning for fallback translations for numbers and dates still occur, completely littering the console.

This fix makes all fallback warnings to vanish (including numbers and dates) upon setting the `silentTranslationWarn` flag, while leaving other (non-fallback) warnings intact.
