Update example for INLINE InsertStrategy (#680)
Update example for INLINE InsertStrategy (#680)

Change the example so as to distinguish it from EARLIEST and NEW_THEN_INLINE. The current example may as well have been for either of these strategies.
Need at least 2 empty moments on a qubit to demonstrate this.
