Improvement for a description

This is the italian version for Cockpit -> System -> SSH - Notification about disabling weak cyphers. No errors whatsoever. My hint is to change it form this to
Disabilita cifrari deboli: le connessioni SSH saranno stabilite solo con cifrari più forti e sicuri.


github PR if behind you need to modify the english text else transifex is your friend I bet

Nothing changed, no need to change that right now.
