Create workflow example RAPIDS in Marimo

[ncclementi]

xref: #716

Once we had the guide we can link to an example and have a workflow that shows that.

We have this as a POC that @dmadisetti put together: https://molab.marimo.io/notebooks/nb_TwJxv6bBDvB4DupVmdDLeZ

We should try to polish this and show it and add some text to make it a bit more round.
