Fixes voila-dashboards/voila-reveal#22.

[jtpio]

Thanks!

[jtpio]

Converting to draft for now so we can get a new 0.2.x release out, before targeting 0.3.0 on master.

[jtpio]

Rebased to pick up the CI fix from #934

[jtpio]

Is that something we would still like to get in for 0.3.0? #991

[jtpio]

Rebased onto the latest main

Hello, is this PR ready for review?

[jtpio]

I would say yes.

Maybe we can also bring the example notebook here if the voila-reveal repo is going to be archived in the future: https://github.com/voila-dashboards/voila-reveal/blob/master/notebooks/reveal.ipynb

[jtpio]

To test on Binder:

https://mybinder.org/v2/gh/SylvainCorlay/voila/reveal?urlpath=voila/tree

[jtpio]

Looking good:

[trungleduc]

LGTM, thanks!
