Configure Issue Templates to prevent the opening of documentation Issues in this repo

We're seeing users opening Issues in this repo that pertain to the documentation (e.g. #370 and #362 ).
Documentation Issues should be opened in the top-level repo. An issue template or alternative mechanism would guide users, explaining that this repo contains only a downstream copy and is not the right place for corrections.

未指定檔案或測試。首先檢查此 repository 的 GitHub issue-template 設定以及所參照的文件 issues（#370 和 #362）；當尋求文件更正的使用者被明確引導至頂層 repository 時即視為完成。

由索引模型根據 Issue 內容生成。
