docs: @namespace decorators 
  This decorator allows you to specify the SCHEMA getter and associated
  string as a parameter to the decorator itself. So, for example:
  
  <code>
  @Schema(`
  type Item {
  name: String
  cost: String
  }
  `)
  export class Item extends GQLBase {
  // ...
  }
  </code>
