Replace data URL in big_patent dataset and support streaming
_The documentation is not available anymore as the PR was closed or merged._ I first uploaded the data files to the Hub: I think it is a good option because we have git lfs to track versions and changes. Moreover people will be able to make PRs to propose updates on the data files.
- I would have preferred to upload it it to the "data" org namespace, but it is already taken (although not used): might be possible to take it?

As an alternative (and to be consistent with previous datasets), I also uploaded the data files to our AWS bucket.

We should decide which to use (now and for future datasets) and set it here before merging. We should remove the data files for the non-chosen option.

CC: @lhoestq @mariosasko @polinaeterna  Would it make sense to make the dataset a community one (so, create an organization for it) and store the script and the data in a single repository? Just as it is for most of the datasets. That way we can also access the data using a relative path inside the repo (that's not the point though). The point is that to me it seems a bit more straightforward to store everything in one place. 

I guess the strong argument against this logic is that in this case the canonical version won't work... But maybe there is some redirecting mechanism I don't know about? :)

Anyway, I'm in favor of hosting data on the Hub instead of AWS :)  I also think storing everything in one place/single repository is the best option.

@polinaeterna Canonical datasets also support data files (see the [`red_caps` repo](https://huggingface.co/datasets/red_caps/tree/main) for instance)  Thanks @polinaeterna and @mariosasko for your comments.

Yes, definitely it is much better to have everything in the same repo. 

I'm transferring their data files to the Hub under "big_patent" and deleting them from the other repo and AWS.
This PR replaces the Google Drive URL with by our Hub one, once the data owners have approved to host their data on the Hub.

Moreover, this PR makes the dataset streamable.

Fix #4217.
