i18n-it: remove bogus fuzzy translations for revset
The translations were all random fuzzy strings, which can only do harm, so
remove them.
Moreover, given the status of revset (it seems mostly an internal undocumented module, and
to understand it you need the source anyway), I prefer not to translate it for
now.
