Cleanup completed Microsoft To Do tasks

Summary

Microsoft To Do is my task management tool of choice, I use it for tracking everything I do, which means I generate and complete a lot of tasks during a working week. This script iterates across all of the task lists and removes the tasks that have been marked as complete.

Warning

Please be aware this script contains a command that will remove or delete an artifact, ensure you test and understand the implications of running the script.
