editor.codeActionsOnSave with extension slows down file saving in VS Code

まだ誰も着手していません。

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

Visual Studio Code Extension (sumneko.lua)

### Which OS are you using?

Windows 11 Pro 22H2 22621.2134

### What is the issue affecting?

Other

### Expected Behaviour

I have a huge lua file with a ~3k lines in a big workspace folder with ~1k lua files.
I expect that the file is saved instantly, as it was before when I used Windows 10.

### Actual Behaviour

But a week ago I switched to Windows 11 and now I noticed that saving the file takes about 2 seconds.
**When the lua-language-server extension is disabled in VS Code, the file is saved instantly.**
I tried to set `Workspace Event - None` and disable Diagnostics but it didn't help

### Reproduction steps

1. Change large lua file
2. Press Ctrl+S
3. Wait 2 seconds before the extension allows VS Code to save the file to disk

### Additional Notes

I found a stall message
```
File saving "sv_player.lua": Getting the code action from "'Lua'"
([configure] (command:workbench.action.openSettings?%5B%22editor.codeActionsOnSave%22%5D)).
```

### Log File

_No response_

ソースファイルもテストも指定されていません。説明されている大きな Lua ファイルと workspace を使って Visual Studio Code で遅延を再現し、その後、拡張機能の editor.codeActionsOnSave の処理と "Getting the code action" での停止を追跡してください。拡張機能を有効にした状態で保存しても報告された遅延が発生せず、このシナリオのリグレッションテストによるカバレッジが追加されていれば完了です。
