Consider scanning for GraphQL schemas in all graphql folders in the classpath

[sbrannen]

GraphQlProperties.Schema currently uses classpath:graphql/**/ as the resource pattern which limits schema discovery to the first graphql folder found in the classpath.

spring-boot/spring-boot-project/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/graphql/GraphQlProperties.java

Line 75 in bad11bb

private String[] locations = new String[] { "classpath:graphql/**/" };

If this is intentional, please ensure that this is well documented.

If it's not intentional, consider using classpath*:graphql/**/ instead.
