eval doc does not pass test

[mikekgfb]

🐛 Describe the bug

#1383 enables run-docs evaluation to extract a test script from eval documentation,
to run evaluation script. In turn, this extracts the command

python3 torchchat.py eval stories15M --tasks wikitext --limit 10

from the eval doc as a test to ensure that the doc is in fact correct. This appears to be a correct use of eval to me, yet it fails when running as follows:

@vmpuri Can you take a look?

Maybe the doc is outdated
