Printing a QueryBuilder-derived class should show a GraphQL style type definition of the class

[ericbstie]

import gqlrequests

class Episode(gqlrequests.QueryBuilder):
    name: str
    length: float

class Character(gqlrequests.QueryBuilder):
    name: str
    appearsIn: list[Episode]

print(Character)

should print out:

type Character {
    name: String
    appearsIn: [Episode]
}
