Errors without messages

[BroiSatse]

At the moment validation contract returns nice human-readable errors via translation backend. Being a robot, I do not like it and I'd prefer pure data object/hash to be returned.

Justification: I don't think it is contract responsibility to translate it's errors. When used within API, all the i18n normally happens on the client side, so API can be completely translation-free.

Examples

class MyContract < Dry::Validation::Contract
  json do
    required(:name).filled(:string)
    required(:age).filled(:integer)
  end

  rule(:age) do
    key.failure(:too_young, min: 32) if age < 32
  end
end

contract = MyContract.new
errors = MyContract.new(age: 28).errors

errors.to_h # => {
                   name: [{error: :missing}]
                   age: [{error: :too_young, min: 32}]
                 }

(The above is only example response, I have no strong preference/opinion on how that data should be represented)
