If you are opening a PR for Official Notebooks under the notebooks/official folder, follow this mandatory checklist:

• [x] Use the notebook template as a starting point.
• [x] Follow the style and grammar rules outlined in the above notebook template.
• [x] Verify the notebook runs successfully in Colab since the automated tests cannot guarantee this even when it passes.
• [ ] Passes all the required automated checks. You can locally test for formatting and linting with these instructions.
• [ ] You have consulted with a tech writer to see if tech writer review is necessary. If so, the notebook has been reviewed by a tech writer, and they have approved it.
• [x] This notebook has been added to the CODEOWNERS file under the Official Notebooks section, pointing to the author or the author's team.
• [x] The Jupyter notebook cleans up any artifacts it has created (datasets, ML models, endpoints, etc) so as not to eat up unnecessary resources.

Instead of a bigquery-ml folder, can you put it in the model registry folder? This repo is for demoing Vertex AI so it should highlight the Vertex AI product.

For BQ notebooks, they have their own repo: https://github.com/GoogleCloudPlatform/bigquery-notebooks
