Update Node.js to 22.x on GitHub Actions to fix CI ReadableStream error (#979)

This also updates snippet names of the type "[name] method of [class]"
to correctly reference the class that defines them.

For example, _draw() was labelled as "of Node" before, but it's actually
CanvasItem which defines this function.
