Handle invalid `>=16.8.0 && <=^19.0.0` constraint in package.json dependency values

npm considers this as just being >=16.8.0, but maybe we should be smarter about this?

This is somewhat related, though the concern is specifiers that don't have support here in the first place:

That's different because it's related to specifiers. This is for in a package.json dependency entry. For specifiers we would never allow invalid ranges like this and instead surface an error so the user knows it's invalid.
