[stable-2.7] Update win_scheduled_task.py (#46720)

* Update win_scheduled_task.py to document that the duration of a task trigger can be null, which will cause it to run indefinitely - docs update makes use of suboptions

* Add a fix for the validate-modules schema
(cherry picked from commit 0bc5b79)
