AK: Make JsonParser correctly parse unsigned values larger than u32

Browse Source 
Prior to this, it'd try to stuff them into an i64, which could fail and
give us nothing.
Even though this is an extension we've made to JSON, the parser should
be able to correctly round-trip from whatever our serialiser has
generated.
