Dataset used in example on scatter plots page is removed in geopandas 1.0

This example here won't run with later versions of geopandas

https://plotly.com/python/scatter-plots-on-maps/#basic-example-with-geopandas

```
import plotly.express as px
import geopandas as gpd

geo_df = gpd.read_file(gpd.datasets.get_path('naturalearth_cities'))

px.set_mapbox_access_token(open(".mapbox_token").read())
fig = px.scatter_geo(geo_df,
                    lat=geo_df.geometry.y,
                    lon=geo_df.geometry.x,
                    hover_name="name")
fig.show()
```

```
     20     error_msg = (
     21         "The geopandas.dataset has been deprecated and "
     22         "was removed in GeoPandas 1.0. New sample datasets are now available "
     23         "in the geodatasets package (https://geodatasets.readthedocs.io/en/latest/)"
     24     )
```

It would be good to have an example that works with earlier and later versions of geopandas
