Pin hard Voila

[martinRenou]

Voici does not work with Voila 0.5.0a5.

Let's make a patch release that pins it. I will try to come up with a PR that brings support for it.

What is it that makes it not work? The JupyterLab 4 update?

[martinRenou]

Probably yes. Though we cannot update Voici to JupyterLab 4 because of JupyterLite.

It's probably also just due to the voila template changes in this PR.

There are multiple issues resulting in the CI to fail on master:

• pandas >=2.0 is broken on emscripten-forge (need @atrawog's help on this)
• latest jupyterlab_widgets build is incompatible with what Voici uses. This is not possible to fix unless we rebuild Voici with that latest version -> trying this results in having multiple versions of Lumino (v1 and v2) and JupyterLab packages (v3 and v4) and the build fails. This is because jupyterlite needs JupyterLab v3, and for some reason yarn's dedupe does not work.
  I think the only solution here would be to pin jupyterlab_widgets and ipywidgets in the emscripten-forge environment (in jupyterlite-xeus-python?)
• latest Voila build is against JupyterLab 4, which is not possible to use because of jupyterlite -> we need to pin Voila
