Fixed 'en' translations and added 'it' translations

[BoGnY]

The en translation was wrong.

If you use ValidMoney(min: 10, max: 100) which I assume means 10 < value < 100 and pass 1 as the value, the english error was The value must be less than 10 which makes no sense because 1 is less than 10 😅

The french translation is indeed correct: Cette valeur doit être supérieur à 10.

I took this opportunity to add the Italian translation.
