Remove deprecated methods:

• set_access_token
• unset_access_token
• read_from_credential_store
• write_to_credential_store
• erase_from_credential_store

All of those are related to git credentials management. The preferred methods are not set_git_credentials and unset_git_credential. Their main advantage is to respect the user preferences in term of git credential helper instead of assuming git-credential-store should be used. Read #1051 and #1138 for more details.

I also took the opportunity of this PR to refactor some tests that were using set_access_token.

---

set_access_token was use in other HF repos. However, it was only for testing purposes and seemed to be legacy copy-pasted code (i.e. I don't except a lot of third-party libraries to use it). Here are the PRs to fix that:

• datasets: Remove set_access_token usage + fail tests if FutureWarning datasets#5623
• transformers: Remove set_access_token usage + fail tests if FutureWarning transformers#22051
• hffs: Remove use of set_access_token in tests + small refacto hffs#15

Yes, looks good to me! I've quickly verified and it seems like this won't impact transformers. Let's remember to still launch the full test suite in downstream libraries to ensure nothing breaks.

I'll do so for transformres once this PR is merged in!

[Wauplin]

Thanks for the review! As said in the PR description, I tried to take care of the breaking changes in transformers, dataset and hffs pipelines. But yes, definitely a good idea to merge it and try for real :)

(I'm merging it btw)

[LysandreJik]

Great, will give it a try now and report here ASAP
