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

Follow-up toGoogleCloudPlatform/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 canremove that copy and remove the Jupyter/IPython depedencencies from`samples/snippets/requirements.txt`.Thank you for opening a Pull Request! Before submitting your PR, there are a few things you can do to make sure it goes smoothly:- [ ] Make sure to open an issue as a [bug/issue](https://github.com/googleapis/python-bigquery/issues/new/choose) before writing your code!  That way we can discuss the change, evaluate designs, and agree on the general idea- [ ] Ensure the tests and linter pass- [ ] Code coverage does not decrease (if any source code was changed)- [ ] Appropriate docs were updated (if necessary)
