Prompt the user to authenticate when connecting to a device

[bigdiff]

Currently when attaching to a vscode on another machine you have to authenticate. But the authentication link is hidden inside the extension logs accessed through the output tab next to the terminal tab in vscode.

Other extensions I've used can show a prompt to open/copy the link and open it in the default browser. This will improve the UX a lot because the timeout is really low so the first connection fails then you can copy the link open it in the browser login and authorize then try to connect again.
