[DOC]: Spatial relationships not documented in Python User Guide

How would you describe the priority of this documentation request

Medium

Is this for new documentation, or an update to existing docs?

New

Describe the incorrect/future/missing documentation

I think the new spatial relationship predicates should have examples in the API examples docs in the user's guide. They are methods on GeoSeries, so currently they are only documented in the API reference. But I think some examples here: https://docs.rapids.ai/api/cuspatial/stable/user_guide/cuspatial_api_examples/ would be good.

If this is a correction, please provide a link to the incorrect documentation. If this is a new documentation request, please link to where you have looked.
