[MDC-iOS/BottomSheet] Fix dismissOnDraggingDownSheet behavior

The bottom sheet incorrectly allowed the sheet to be drag dismissed when `dismissOnDraggingDownSheet` was set to NO.

This change permits the gesture to dismiss to begin but prevents it from actually closing the sheet.

Closes material-components#9885
