Feature Request: allow opening remote workspaces through extensions

Hey 👋

I am developing a home screen extension that helps to manage different workspaces. One of my requirements is to allow opening remote workspaces, e.g. codespaces, remote machines etc.. Unfortunately there is not documentation about that and it appears to me that vscode.openFolder is not capable doing that. So far I know:

• vscode.env.remoteName gives me the environment type, e.g. codespaces, which allows me to determine whether the workspace is local or remote
• while searching this repo for more information I found that there is something like remote-containers.openFolder which is not documented though nor do the examples I found make any sense to me
• I know VSCode is able to open codespaces through a like like vscode://github.codespaces/connect?name=<codespace-id> but creating a vscode.Uri in that form doesn't work

Any help on that matter is appreciated.
Thanks!
