FR: Option that "Ignore this line" Code Actions adds to this line instead of the one above

還沒有人認領這個 Issue。

Right now, when using the "Ignore this line" code action, it adds this line above the respective line:
```lua
---@diagnostic disable-next-line: rulename
problemline
```

However, I often prefer this type of line ignoring
```lua
problemline ---@diagnostic disable-line: rulename
```

while it works and is correctly recognized by the lsp, there is no code action and/or no option to add such a comment, I have to change this manually.

The eslint-lsp, for example, [has an option for the ignore-line-code-action which accepts `sameLine` or `separateLine`](https://github.com/microsoft/vscode-eslint/blob/55871979d7af184bf09af491b6ea35ebd56822cf/server/src/eslintServer.ts#L2119).

先找出「Ignore this line」程式碼動作的 language server 實作，以及其設定的定義方式。比較現有的 disable-next-line 行為與所要求的同一行 disable-line 形式；完成條件是使用者可以透過選項選擇放置位置，且產生的 Lua 註解能正確被辨識。
