Update caching examples with the latest API

[NivekT]

🐛 Describe the bug

Now that the PR related to the refactoring of on_disk_cache is merged, we need to update the caching examples to reflect the latest API.

Wait. I thought I had updated them.

Actually you are right, not sure what I was looking at.

The only one might be this:
https://github.com/pytorch/data/blob/main/examples/text/CC100.ipynb

Is .end_caching needed within def CC100(...)?

[ejguan]

You are right. I didn't modify the notebook files. Send a PR later. Thanks

Closing as the PR is landed.
