Equivalent of the "Voila preview extension" for Voici

[jsignell]

Problem

I have now spent some time developing a voici dashboard and my process looks like:

1. build the notebook for jupyterlite
2. open jupyterlite in a new private window to avoid any previous state
3. make changes and run notebook to make sure things are working
4. download the notebook
5. build the notebook for voici
6. check that things look right
7. push the changes to github

Proposed Solution

It would be great to use the voila extension in jupyterlite to render voici.
