Adjust comment to reflect the move away from the binder-examples repo
-# A binder requirement file is required by sphinx-gallery. We don't really need
-# one since the binder requirement files live in the
-# scikit-learn/binder-examples repo and not in the scikit-learn.github.io repo
-# that comes from the scikit-learn doc build. This file can be removed if
-# 'dependencies' is made an optional key for binder in sphinx-gallery.
