Prior to this commit, the `spring.graphql.schema.location` would only allow a single file as the source for the GraphQL schema. This commit changes this configuration to `spring.graphql.schema.locations` so that it accepts actual locations (folders) and scans for `*.graphqls` files in those locations. All files are parsed and merged as a single GraphQL `TypeDefinitionRegistry`. Closes gh-56
