Describe the problems or issues found in the documentation
Currently this notebook (and other notebooks that use Dask) isn't being validated in our CI

cudf/ci/test_notebooks.sh

Line 52 in 6238745

# Skip all notebooks that use dask (in the code or even in their name)

And it's likely that #20925 broke something in this notebook when run by-hand.

Suggested fix for documentation

1. Create 2, 10 minutes to [cuDF|Dask-cuDF] notebooks so we can at least validate a (probably commonly seen) introductory cuDF notebook
2. Investigate other notebooks that might be running Dask and split them out into other notebooks if appropriate. (The CI currently only skips validating 10min.ipynb because of Dask usage)
