Describe the Bug

I'm trying to follow the documentation, but when I run the code from Testing section I get the error GraphQLError("Unknown argument 'title' on field 'Query.books'.", ....

It's said that we should use the schema from the Getting Started tutorial. The code is:

import typing
import strawberry

@strawberry.type
class Book:
    title: str
    author: str

def get_books():
    return [
        Book(
            title="The Great Gatsby",
            author="F. Scott Fitzgerald",
        ),
    ]

@strawberry.type
class Query:
    books: typing.List[Book] = strawberry.field(resolver=get_books)

schema = strawberry.Schema(query=Query)

I think we have to either add title parameter to get_books or remove title parameter from TestQuery.

Ready to send a PR if it's needed
