.editorconfig or defaultConfig formatting not respected

还没有人认领这个 Issue。

I'm using neovim 0.7 with lsp-installer and files are not being formatted with the requested configuration in both cases.

_ls -lisa ~/.config/nvim/lua/plugins/_

_.editorconfig_

```
[*.lua]
# [basic code reformat option]
# optional space/tab
indent_style = space
# if indent_style is space, this is valid
indent_size = 4
```

_nvim-lspinstall.lua_

```
local status_ok, lsp_installer = pcall(require, "nvim-lsp-installer")
if not status_ok then
return
end

lsp_installer.on_server_ready(function(server)
local opts = {}
if server.name == "sumneko_lua" then
opts.settings = {
Lua = {
diagnostics = {
globals = { "vim" }
},
format = {
enable = true,
defaultConfig = {
indent_style = "space",
indent_size = "4",
}
},
}
}
end

server:setup(opts)
end)
```

I use the command `lua vim.lsp.buf.formatting()` but the code is formatted with the default values (8 spaces I think)

首先，使用所示的 .editorconfig、nvim-lspinstall.lua 设置和 lua vim.lsp.buf.formatting() 命令重现报告。跟踪语言服务器如何接收格式化配置，并验证 Lua 文件的格式化遵循 indent_style=space 和 indent_size=4，而不是报告中的默认值。
