Points reference guide is not about points

I'm trying to improve the docstring of `.points`. I don't really know what it is and how it differs from `scatter`. The docstring does not provide any helpful information currently either. So I jump to the reference documentation.

But the [Points Reference Documentation](https://hvplot.holoviz.org/reference/geopandas/points.html) does not explain what `points` is and how if differs from `scatter`. Furthermore it does not use `kind='points'` or `.hvplot.points` anywhere. It only showcases `geo=True`.


From this I have no chance of understanding what `points` is. And I end up quite confused.

Please fix. Thanks.
