Cannot install addons that aren't installed that are defined by a `${addon}` path in `.luarc.json`

还没有人认领这个 Issue。

### Which OS are you using?

Windows

### Expected Behaviour

An "Install" button on the addon

### Actual Behaviour

A "Disable" button that when clicked errors

### Reproduction steps

1. Have no addons installed through the addon manager
2. Open a folder that already has a `.luarc.json` with `workspace.library` pointing to a path with `${addons}` placeholder (e.g. `"${addons}/garrysmod/module/library"`)
3. Try to install the addon through the addon manager to see that you only get a "Disable" button

### Additional Notes

The only workaround is to open another folder/workspace and then enable the addon manually.

It would also be nice to have a settings option you can throw into `.vscode/settings.json` to prompt the user to install addons required by the folder/workspace if they don't already have it installed.

从 addon 管理器对 .luarc.json 中 workspace.library 路径的处理，以及报告中描述的 getAddons、install 和 disable 入口点开始。所有 addon 均未安装时，使用 ${addons} 复现 Windows 情况，然后验证 addon 会显示 Install 按钮，并且可以安装而不会出现路径不存在错误。
