Overture example doesn't work because overture deleted their data

[kylebarron]

The overture-geoparquet example doesn't work anymore

> aws s3 ls s3://overturemaps-us-west-2/release/
                           PRE 2025-09-24.0/
                           PRE 2025-10-22.0/

From the overture slack:

That is so dumb. I'll let someone else update the notebook (it should be possible to list the releases in the bucket and choose one)
