Make it so npm tasks can be run from markdown-based text in steps

[BrianRosamilia]

(Partially from #39 )

A suggestion that would have really helped me and I think would be amazing and really set this project ahead of traditional presentation tools :

I was glad to see the tour steps support markdown.

So when I type npm run storybook it shows how I expect it and how another developer would like to read it.

But it would be great if typing that was translated to

▶️ npm run storybook

And clicking the play button would actually run the task.

I was using Codetour to do a live presentation to a group of developers and it was slightly cumbersome to use my (extremely loud) mechanical keyboard to show a few new npm tasks. It would've been great to just click a button and show a task running.

Thanks for reporting this! I absolutely want to enable this :) It's currently dependent on a change in VS Code itself, and so once that's shipped, I'll add support for this: microsoft/vscode#93034.

This feature has been shipped in the latest extension update. In a step comment, you can now embed a shell command using the following syntax: >> npm run compile, where npm run compile is an arbitrary shell command. That syntax will be converted into a hyperlink, that when clicked, will run the shell command in the VS Code integrated terminal.

Let me know if you have any feedback on this experience!
