add story_cloze
Thanks for pushing this dataset :)

According to the CI, the file `cloze_test_val__spring2016 - cloze_test_ALL_val.csv` is missing in the dummy data zip file (the zip files seem empty). Feel free to add this file with 4-5 lines and it should be good

And you can fix the YAML tags with
```yaml
pretty_name: Story Cloze Test
```
and filling the other tags task_categories and task_ids

If the dataset doesn exist on paperswithcode, you can just leave
```yaml
paperswithcode_id: null
``` @lhoestq can't fix the last test fails. > Thanks @zaidalyafeai, the failing test is due to an issue in the master branch, that has already been fixed.
> 
> You can include the fix:
> 
> ```
> git checkout add_story_cloze
> git fetch upstream master
> git merge upstream/master
> ```

Thanks @albertvillanova, passed all the tests now.  Thanks Albert, I fixed the suggested comments. This dataset has no train splits, it is only used for evaluation.
