Thanks !

I also updated the dataset_infos.json to register the new url :)

The CI is failing because the dataset tags for discofuse are missing. I'm merging this PR since this is unrelated to this PR, but feel free to open another PR to add the tags here if you have some time:

datasets/datasets/discofuse/README.md

Lines 1 to 5 in 19408f9

	---
	languages:
	- en
	paperswithcode_id: discofuse
	---

The missing tags are:

'annotations_creators', 'language_creators', 'licenses', 'multilinguality', 'pretty_name', 'size_categories', 'source_datasets', 'task_categories', and 'task_ids'

Thanks again !
