[Feature Request]: 为 GraphQL Subject.Character 添加 actors

[Him188]

https://api.bgm.tv/v0/graphql

fragment SubjectFragment on Subject {
  id
  characters {
    type
    character {
      id
      actors # expected
    }
  }
}

query BatchGetSubjectQuery {
  s0:subject(id: 425991){...SubjectFragment}
}

HTTP API 支持获取 actors, 希望为 GraphQL 也增加
