* docs(samples): add create table hive partitioning sample

* refactor

Follow-up to GoogleCloudPlatform/python-docs-samples#6889, which removed a BigQuery magics sample for using query parameters.

Note: jupyter_tutorial_test.py is a copy of what is in the `samples/snippets`
folder. Once the docs have been updated to point to this new version, we can
remove that copy and remove the Jupyter/IPython depedencencies from
`samples/snippets/requirements.txt`.
