[Coop] Hybrid Destroyers use outdated WoL Graviton Prison effects

In Heart of the Swarm, an updated set of effects for the Hybrid Destroyer ability “Graviton Prison” was created. The beam used by the ability was made a bit wider, and the effect model itself was completely redone; instead of resembling a blue wireframe ball it was updated to be a tumultuous purple orb. Unfortunately, these updated effects have not carried over into coop; the ability uses the old effects from Wings of Liberty, including the thinner version of the beam and the blue wireframe ball.

The current models used by the ability are “HybridGravitronPrisonBeam” and “HybridGravitronPrisonImpact”. The models it should use are “HybridGravitronPrisonBeamSwarm” and “HybridGravitronPrisonImpactSwarm”.
