Issues with the vanilla docs

There's a number of small fixes needed for the documentation.

1. in the index.html file, root needs to be a canvas not a div.

const root = new Root(camera, renderer, undefined, {
    flexDirection: "row",
    padding: 10,
    gap: 10
})

should be something more like

const root = new Root(camera, renderer,  {
  flexDirection: 'row',
  gap: 30,
  width: 500,
  borderRadius: 10,
  padding: 10,
  alignItems: 'center',
  backgroundColor: 'red',
  overflow: 'scroll',
})

(Some of these options might be unnecessary but the first one created a ui that wasn't visible.)

The example here works much better than the documentation. https://github.com/pmndrs/uikit/tree/main/examples/vanilla
