Connect to a coder workspace from vscode.dev

Can a Coder workspace be connected from [vscode.dev](https://code.visualstudio.com/docs/editor/vscode-web)?

Coder vscode extension uses the coder binary to connect to workspaces, so without a native WASM binary, it doesn't look possible.

Investigating and, if possible, implementing this should be nice to have.

It is possible to run extensions in the browser vscode version. See https://code.visualstudio.com/blogs/2021/10/20/vscode-dev#_extensions

Here is a guide to author web extensions: https://code.visualstudio.com/api/extension-guides/web-extensions

Edit:
I am not sure how different [`vscode.dev`](https://code.visualstudio.com/docs/editor/vscode-web) is (in terms of features) from [Microsoft vscode server](https://code.visualstudio.com/docs/remote/vscode-server).

首先，將 Coder VS Code extension 的連線流程與 vscode.dev web extensions 的功能和限制進行比較。閱讀連結的 vscode.dev 和 web-extension 指南，並將其與所參考的 VS Code Server 文件進行比較。完成的標準是確定以瀏覽器為基礎的工作區連線是否可行；如果可行，則定義實作範圍。
