Consider giving priority to added paths over gitignore files

還沒有人認領這個 Issue。

Hello.
I was trying to make the VSCod extension detect my hammerspoon definitions, and it was not working.
Then I noticed the `"Lua.workspace.useGitIgnore": false` setting, and after setting it to false it started working.

I have this in my third party config
```
"Lua.workspace.userThirdParty": [
"/private/etc/nix-darwin/dotfiles/hammerspoon/Spoons/EmmyLua.spoon/annotations/"
]
```

That `annotations` folder is gitignored, but I seriously think it should take priority over the gitignore setting, because I manually added it.

首先追蹤在篩選 workspace 路徑時如何處理 Lua.workspace.userThirdParty 和 Lua.workspace.useGitIgnore 設定。檢查所提供的 annotations 路徑的行為，該路徑會被 gitignore 忽略，但已明確設定。當明確新增的路徑即使在 gitignore 設定下也會被納入考量，同時其他路徑的既有行為維持不變時，即視為完成。
