Custom error status for readValidatedBody, readValidatedQuery, etc

[cosbgn]

Describe the feature

I love readValidatedBody but 400 as status error is too generic, I use it for all sort of errors and I would like to have the ability to set a better error code.

Ideally it would simply be: readValidatedBody(event, schema.parse, 422)

it can be 400 as default so it wouldn't be a breaking change, even tough I would personally prefer 422
