Propose a new feature #6

I just thought you could add something on the Rubber Duck feature as part of the workshop.

https://docs.github.com/en/copilot/concepts/agents/copilot-cli/rubber-duck

It would be great for others to learn about this new feature.

The Copilot CLI Rubber Duck agent gives people a way to talk through their problems and clarify their thinking.

@jamesmontemagno -

Note: This workshop is defiantly a good way to get up to speed with learning CLI too :)

Thanks
