Use sandpack for a built-in editor experience

[JRJurman]

Summary

With the release of sandpack, we have a really easy built-in way to provide a straightforward experience for users to play around with tram-one right in the web site! This would be super cool, and potentially a great way to provide an experience that allows people to play around with the existing code.

One potential way this could work is by having a button that can open a modal (or embedded view) on a piece of code that exists on the site - conversely, we could have it as its own dedicated page!

While we are deferring to CodePen for our examples, it might be nice to build a dedicated editor that we could link to 🤔
