README out of date / missing example

[bglw]

👋

The current repository README contains:

Web Assembly

This interpreter can be exposed to JavaScript! You can build the example locally with:

npm run build

In the console you can use window.evaluate to pass JavaScript in. To develop on the web assembly side you can run:

npm run serve

then go to http://localhost:8080.

From what I can tell, the package.json file containing the npm run build script was entirely removed in #3787 so this hasn't been applicable in a while.

Is there an alternative build suggestion for spinning up a wasm example, or should this section just be removed from the README?
