Trac #25960: Minor Toggling Documentation Fixes

There are some minor issues with documentation for
toggling/rowmotion/birational rowmotion methods that live in
categories/finite_posets.py , because they refer to the methods
order_ideal_toggle() and order_ideal_toggles() as if they live in the
same file (but they actually live in categories/posets.py).
