Error in pystac/docs/tutorials/how-to-create-stac-catalogs.ipynb

There is erroneous code in the "How to create STAC catalogs" tutorial.
In the section about adding the eo extension to an Item object, the code throws an AttributeError:

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
Input In [35], in <cell line: 7>()
      1 eo_item = pystac.Item(id='local-image-eo',
      2                       geometry=footprint,
      3                       bbox=bbox,
      4                       datetime=datetime.utcnow(),
      5                       properties={})
----> 7 eo_item.ext.enable(pystac.Extensions.EO)
      8 eo_item.ext.eo.apply(bands=wv3_bands)

AttributeError: 'Item' object has no attribute 'ext'

The syntax for this in pystac/docs/tutorials/creating-a-landsat-stac.ipynb is different, but I can't see how to rewrite this code in the same way.

Any help much appreciated.

@davedavemckay check out #775 for the new syntax for using extensions.
