zh-cn/cli/_sidebar.md导航文件中所有链接地址都多加了 "/cli/" 导致点击链接不跳转

zh-cn/cli/_sidebar.md 文件摘录：
```
* [[cli 概述](typora://app/cli/README.md)](/cli/README.md)
* cli 命令
* [[用户账号操作](typora://app/cli/user.md)](/cli/user.md)
* [[关闭/打开项目](typora://app/cli/project.md)](/cli/project.md)
```
README.md、user.md这些文件实际上应该是与_sidebar.md同级，直接用 `[xxxx](/README.md)` 即可。

Open zh-cn/cli/_sidebar.md and review each navigation link against the files in the same directory, including README.md, user.md, and project.md. Remove the extra /cli/ path segment so the links use the files' actual sibling paths, then verify that every sidebar link navigates correctly.
