native-image: Missing resource hints for schema definitions

[mhalbritter]

When running the native-image from the spring-native sample cloud-task on the sb-3.0.x branch, i get the following exception:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'taskRepositoryInitializer': Cannot read SQL script from class path resource [org/springframework/cloud/task/schema-h2.sql]

I guess there's a resource hint missing.
