Title: Prepare tests for hfh 0.14
Author: Wauplin (CONTRIBUTOR)
State: closed
Created: 2023-04-24T12:13:03Z

Related to the coming release of `huggingface_hub==0.14.0`. It will break some internal tests. The PR fixes these tests. Let's double-check the CI but I expect the fixed tests to be running fine with both `hfh<=0.13.4` and `hfh==0.14`. Worth case scenario, existing PRs will have to be rebased once this fix is merged.

@albertvillanova thanks for the review. As you prefer for the github CI config. I just took it from @lhoestq's branch when testing hfh==0.14.0. I think it's still relevant for next releases. In any case, I let you handle merging the PR :)
