Issue: XNLI dataset is not loading 
State: closed

`dataset = datasets.load_dataset(path='xnli')`

showing below error 
```
/opt/conda/lib/python3.7/site-packages/nlp/utils/info_utils.py in verify_checksums(expected_checksums, recorded_checksums, verification_name)
     36     if len(bad_urls) > 0:
     37         error_msg = "Checksums didn't match" + for_verification_name + ":\n"
---> 38         raise NonMatchingChecksumError(error_msg + str(bad_urls))
     39     logger.info("All the checksums matched successfully" + for_verification_name)
     40 

NonMatchingChecksumError: Checksums didn't match for dataset source files:
['https://www.nyu.edu/projects/bowman/xnli/XNLI-1.0.zip']
```

I think URL is now changed to "https://cims.nyu.edu/~sbowman/xnli/XNLI-MT-1.0.zip"

also i tried below code to solve checksum error 
`datasets-cli test ./datasets/xnli --save_infos --all_configs`

and it shows

Hi !
Yes the download url changed.
It's updated on the master branch. I'm doing a release today to fix that :)

the issue is fixed with latest release
