Describe the bug
The vendor/nuwave/lighthouse/src/Validation/Validator.php validator has the public setArgs method that can be used to add an ArgumentSet to the args pre validation.
Making it possible to retrieve a model and validate its content in certain cases.

There is no way to set the Type property on the Argument that is used in the ArgumentSet which is required by the RulesGatherer class.
This causes the following error to occur:
"debugMessage": "Typed property Nuwave\\Lighthouse\\Execution\\Arguments\\Argument::$type must not be accessed before initialization",
Expected behavior/Solution
Either to be able to set the types manually set it or some sort of parser that resolvers it automatically.

The above(Expected behavior/Solution) answers this question.

Steps to reproduce

1. Have an input with the @validator directive
2. Inside the Validator make use of the prepareForValidation method.
3. Store $args = $this->args in a local variable and set a value, using the $this->args->addValue() method.
4. Call $this->setArgs($args); this should raise the error.
