Set the minimum height to the CheckBox

Root Cause: Touch target of "container" is too small, reported by
accessibility scanner. Suggest to enlarge bigger than 48dp.

Solution: Set the minimum height to the CheckBox layout. If the
container text in CheckBox is bigger than 48dp, it will follow the
layout_height="wrap_content".
