Validation objects could be more useful

[dominictobias]

At the moment if I don't return an expected response that I've typed, Elysia has the following error object:

{
"type": "response",
"validator": {},
"value": {},
"code": "VALIDATION",
"status": 422
}

For large objects it takes me ages to manually check every field of often an array of objects from an external server to see what I've typed too strictly. As far as I can tell this error object has nothing useful like "Expected 'lastPrice' to be a number". It just has the validation schema and the values.

It would be great if there was also a message like messages: ["'subtitle' is required", "'page_number' must be numeric"]. This could also form better UI messages.

as far i know you have to reMap them onError anyway in production validations errors are empty
