Upgrade to datasets@2.16.1
We're still using 2.15.0 from November! We could upgrade to 2.16.1. Release notes: https://github.com/huggingface/datasets/releases/tag/2.16.0 and https://github.com/huggingface/datasets/releases/tag/2.16.1

Main changes to to in datasets-server:
- remove custom code to disable datasets script, and simply pass `trust_remote_code=False` (and `True` for datasets in allowlist)
- check that webdatasets work well, and show it in the docs
- https://github.com/huggingface/datasets/issues/6397:  DatasetNotFoundError and DataFilesNotFoundError are now two different exceptions: see how we should handle them in the code
- https://github.com/huggingface/datasets/pull/6449 / https://github.com/huggingface/datasets/issues/6442#issuecomment-1822561211: ensure it fixes https://huggingface.co/datasets/severo/doc-image-4 (it should show another column with the labels). If so: update the docs and the datasets collection
- something else?

Maybe upgrade to huggingface_hub@0.20.1 at the same time (https://github.com/huggingface/huggingface_hub/releases/tag/v0.20.1 and https://github.com/huggingface/huggingface_hub/releases/tag/v0.20.0) as:
- it brings improvements in globs (required for `load_dataset` speedup)
- we are currently pinning a specific commit, which is brittle
