Package gridstack's JS and CSS as part of the template

[SylvainCorlay]

At the moment we are still getting the gridstack CSS and JS from a CDN. It would probably be better to at least serve that content from the local static directory, before we move to the lab app approach.

Hey guys, are there plans to depend on the npm package instead of baking a copy of static code into your release ?
I see you are on 2.0.0, which is great! but likely to be released with bug fixes as 2.x was quite a re-write... I would prefer to have download count toward my NPM package as well (show usage), but don't know how you create/distribute your package...

Thanks Alain!

Yes we plan to switch the way gridstack is packaged, and probably rely on a package.json with an additional build step.

For reference, gridstack is currently used in 2 different places here:

• The template:

voila-gridstack/share/jupyter/nbconvert/templates/gridstack/gridstack_base.html.j2

<link href="https://cdn.jsdelivr.net/npm/gridstack@2.0.0/dist/gridstack.min.css" rel="stylesheet" />

• The editor as a classic notebook extension (vendored): https://github.com/voila-dashboards/voila-gridstack/blob/ac0c7debddb4169a6ff3eca469d501ff8dc8caf0/voila-gridstack/static/gridstack.js
