Error reading from provided Iceberg buckets in other systems

Despite trying to read from the `s3://clickhouse-datasets/coffeeshop` S3 location, the manifest files reference the `s3://clickhouse-coffeeshop-benchmark/coffeeshop` location, which doesn't appear to be public, and data files can't be downloaded from it.

Start by reproducing the read from s3://clickhouse-datasets/coffeeshop and inspect the manifest references to s3://clickhouse-coffeeshop-benchmark/coffeeshop. Done means the provided Iceberg data can be downloaded and read successfully by the other system, or the access limitation is clearly documented.
