Using `coc-lua` with `coc.nvim` will produce a `.luarc.json` when editing own custom configs that should be excluded from NvChad, since NvChad does not maintain its own `.luarc.json`
One might decide to install coc.nvim which requires to maintain a custom configuration at the root of the `nvim` folder (created with the command `:CocConfig`). It is recommend to ignore the file to avoid update conflicts as NvChad does not ship coc.nvim.
