Expected Behaviour

Producing documentation for the given module

Actual Behaviour

Producing documentation for lua's builtin functions

Reproduction steps

1. Create & cd into empty folder with a module.lua inside:

---@param x number
function foo(x) end

2. Execute lua-language-server --doc=. --doc_out_path=.
3. Get the doc.md & doc.json containing lua docs instead of module docs

Additional Notes

Tested on 3.13.5.

Log File

file_home_girvel_tmp_..log
service.log

从 lua-language-server --doc 命令开始，追踪 --doc=. 和 --doc_out_path=. 如何选择输入模块和输出文件。使用提供的 module.lua 重现该问题，然后验证 doc.md 和 doc.json 描述的是该模块，而不是 Lua 的内置函数。
