Returning `bool` from mutation causes exception.

Describe the Bug

Hi i have a mutation like this:

@strawberry.type
class UserMutation:
    @strawberry_django.mutation()
    def login(self, info: Info, data: UserLoginInput) -> TokenType | None:
        request: HttpRequest = cast(HttpRequest, info.context["request"])
        user = django_authenticate(request, username=data.username, password=data.password)
        if user is not None:
            django_login(request, user)
            token, _ = Token.objects.get_or_create(user=user.pk)
            return token

    @strawberry_django.mutation()
    def logout(self, info: Info, data: TokenType) -> bool:
        pass

and it raises an error like this:

C:\Programming\CoreProject\backend\django_core\apps\gql\mutations\user.py changed, reloading.
