title: No google drive URL for pubmed_qa
comments: _The documentation is not available anymore as the PR was closed or merged._ CI is failing because some sections are missing in the dataset card, but this is unrelated to this PR - Merging !
body: I hosted the data files in https://huggingface.co/datasets/pubmed_qa. This is allowed because the data is under the MIT license.
