Spring Projects that have the `spring.graphql.schema.locations` property
set to `"classpath*:graphql/**/"` as suggested in the documentation have
failing GraphQL tests after upgrading to Spring Boot 4.
The `Query` type definition in the books-domain schema clashes with the
schema of the application. Presumably the books-domain schema was never
meant to exist in the exported JAR file. This commit moves it into the
test module to stop it from being exported and causing problems.
