In b/448126500 I suggest investigating the errors that happen when visualizing STRUCT columns, but this PR doesn't test such cases.

When displaying a DataFrame containing JSON columns (including nested JSON in lists or structs), the
anywidgettable would fail to render and fall back to the "Computation deferred" message. This was caused by a limitation in PyArrow (apache/arrow#45262).This branch only updates the relevant notebook. The underlying code fix for handling JSON subfields in STRUCT and ARRAY columns was already merged via PR #2216 (fix: support results with STRUCT and ARRAY columns containing JSON subfields in to_pandas_batches()).
This change simply aligns the notebook with the updated code.
Fixes #<448126500 and 453561268> 🦕
