Fixed the tests that expected bigint to be generated

I like this, time ago I had an issue caused by a number being used as bigint this because the deserialization is just a JSON parse no hard check of struct and transformations like could be done with libraries like zod.

By the way, currently in my project I use the attribute #[ts(type = number)] and this is enough.
