Adds the schema loaded from the given URLs.
If not set, the {@code schema.graphql} or {@code schema.graphqls} will be imported from the resource.

@deprecated Use {@link #graphql(GraphQL)} instead. You can create a {@link TypeDefinitionRegistry}
            using {@link SchemaParser}, and then create {@link GraphQLSchema} using a
            {@link SchemaGenerator}. Then, set it to a {@link GraphQL.Builder}.
