Remove setuptools dependency from requirements-docs.txt for Plone 6.2

plone.restapi has two dependencies to build HTTP request and response examples in the documentation. Work is in progress to use implicit, or more specifically, native namespaces for Plone 6.2.

The following line needs to be removed for Plone 6.2.
