No resource was found in [AWS Public Datasets page](https://s3.amazonaws.com/amazon-reviews-pds/readme.html)

**To reproduce**
mkdir /tmp/reviews/
aws s3 --no-sign-request cp s3://amazon-reviews-pds/tsv/amazon_reviews_us_Digital_Video_Download_v1_00.tsv.gz /tmp/reviews/

**Logs**
fatal error: An error occurred (403) when calling the HeadObject operation: Forbidden
I have ensured my account has full S3 access.

Start with the linked batch_transform_pca_dbscan_movie_clusters notebook and its Data section, then review the amazon-reviews-pds README and the provided AWS CLI reproduction command. Confirm whether the referenced dataset is available and update the example's dataset reference if needed; done means the documented download succeeds without the reported 403 error.
