Add recipe for using Granted CLI with VS Code devcontainers

So there is there a way to get assume to work inside a devcontainer then? I ran into

Granted could not detect an existing installation of xxx at known installation paths for your system

which actually made sense that it couldn't continue, since the host browser wouldn't be visible inside the container.

@jpo-tu you need to use Stdout for a browser option and then it will take you to a sign-in page within a default browser on your host machine.

However, you'll eventually get stuck again with granted requesting a passphrase, as confirmed here too: https://medium.com/@josh.armitage/using-granted-in-a-dev-container-e355a3045c70
