cnn_dailymail with cloud storage does not work

tfds build cnn_dailymail works. fds build cnn_dailymail --data_dir="gs://my-bucket/tensorflow_datasets" doesn't. It gets stuck.

Ubuntu 18.04, Python 3.6.9, TensoFlow 2.6.2, tfds_nightly 4.5.0.dev202201310107.

No source files or tests are named. Start by reproducing the cnn_dailymail build with the gs:// data directory and inspect the extraction stage after downloads complete; done means the cloud-storage build finishes successfully and the failure is covered by a regression test.
