closes#5724
this uses a (potentially bogus) assumption that the lowest mapped meta value associated with an ID is valid. I don't want to break this during a patch release, and this works for now.
In the future it would probably make more sense to bypass ItemTranslator entirely, and rely solely on the blockstate returned by RuntimeBlockMapping to fetch the correct ID. This is similar to how we serialize items for saving on disk in PM5.
I've stuck to only doing this in the places where I'm sure we should never get false back. Other places I'm less sure of (and I found more bugs along the way).
this is not as good as phpstan/phpstan-src#769 (e.g. array_key_first()/array_key_last() aren't covered by this, nor is array_rand()) but it does eliminate the most infuriating cases where this usually crops up.
