`.luarc.json` can't work with lua-language-server

I have installed `lua-language-server` and tried to create a Lua config file, but it's not working for the LSP server.

```
helix --healt lua

Configured language server: lua-language-server
Binary for language server: /opt/homebrew/bin/lua-language-server
Configured debug adapter: None
