Describe the bug

The tutorial is failing with the following error:

requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://s3.amazonaws.com/research.metamind.io/wikitext/wikitext-2-v1.zip
This exception is thrown by __iter__ of HTTPReaderIterDataPipe(skip_on_error=False, source_datapipe=OnDiskCacheHolderIterDataPipe, timeout=None)

Since torchtext is no longer supported, suggesting to deprecate unless author suggests otherwise.
