[margalva]

Move the docutils requirement from main dependency to documentation dependency, so it's not shipped with pydynamicreporting.

The last time I checked, this is technically not just a doc dependency but is also necessary for django/serverless to run.

That may not be the case anymore. Can you run a local test of serverless without the dependency and confirm it works? Thanks.

From quick research:
Django itself doesn’t need docutils. The only built-in part of Django that uses it is the optional django.contrib.admindocs app, which renders reStructuredText from docstrings in the admin. If admindocs (or a third-party package that imports it) is in play, you’ll see ModuleNotFoundError: No module named 'docutils' at import time.

We actually do have this in our codebase, although I think this may not be necessary.
