Use the pyodide webpack plugin

[rth]

We should start using https://github.com/pyodide/pyodide-webpack-plugin for this example or even maybe have the example in https://github.com/pyodide/pyodide-webpack-plugin and remove this repo altogether.

The only think we need some webpack example to run in CI.
Any opinion on this @mneil ?

I'm +1 for it. Opened an issue in pyodide-webpack-plugin.

Yep, good idea, forgot this repository existed :). I'll follow up on the other plugin issues then come back to this.
