Describe the Bug

In my app, I would like to have something like:

@strawberry.django.input(Criterion)
class CriterionInput:
  ...

@strawberry.type
class Mutation:
  create_criterion: List[Criterion] = strawberry.django.mutations.create(CriterionInput, handle_django_errors=True)

This generates a mutation with schema:

createCriterion(data: CriterionInput!): CreateCriterionPayload!

I expect this to have a schema of:

createCriterion(data: [CriterionInput!]!): [CreateCriterionPayload!]!

because if handle_django_errors is removed, the mutation has schema:

createCriterion(data: [CriterionInput!]!): [Criterion!]!

I'm able to get the behavior I want by wrapping payload union in DjangoMutationBase#resolve_type with StrawberryList if the original resolved type is an instance of StrawberryList, but I'm not certain it's the correct solution.

I'm still quite new to Strawberry and GraphQL, so apologies in advance if I'm using the API incorrectly.
