Descent of a projectile means it is coming down.
Gravity also pulls objects down.
So force and motion of the projectile are in the same direction.
Work done can be calculated as the product of vector in the direction of motion and force.
So, if the both force and motion are in the same direction, the work done by gravity is positive.
