Adding parent or higher directory to workspace.library of the .luarc.json of a subproject produces erroneous duplicate field/etc warnings

还没有人认领这个 Issue。

### How are you using the lua-language-server?

NeoVim

### Which OS are you using?

Linux

### What is the issue affecting?

Annotations, Type Checking, Diagnostics/Syntax Checking

### Expected Behaviour

No warnings issued for duplicate fields and similar.

### Actual Behaviour

Many warnings about duplicates are produced

### Reproduction steps

Create a subproject and add the parent directory to the subproject's .luarc.json, then create some annotated type and observe warnings about duplicates.

### Additional Notes

It is really a small issue but it would be great to be able to work on subprojects and get require() completions for both the true module name of the project, as well as my other projects within the path

### Log File

_No response_

首先，在 Linux 上的 NeoVim 中，使用一个其 .luarc.json 将父目录添加到 workspace.library 的子项目重现该问题。比较带注解类型和重复字段的诊断，并验证跨项目路径的 require() 补全。完成的标准是：配置不会产生错误的重复警告，同时保留预期的补全。
