improvement it translation

[lonasozo]

forgotPassword string missed, added and translated.

Explanation

forgotPassword string was missed inside the it translation, so the italian version of Metamask still print out the english text. I've added it and translated.

Thank you for the contribution @lonasozo ! I think you've included an extra space at the beginning of the localization key that's making linting fail -- could you fix that?

Thank you!

Ouch, you're right. Should be fixed now
