NetworkCollider2D: could work on any collider shape

NetworkCollider2D could use PhysicsScene2D.OverlapCollider to work on any collider shape. From testing, seems to work fine.

if (col is CircleCollider2D circleCollider)
                    hits = GetCircleCollider2DHits(circleCollider, _interactableLayers);
                else if (col is BoxCollider2D boxCollider)
                    hits = GetBoxCollider2DHits(boxCollider, rotation, _interactableLayers);
                else
                    hits = PhysicsScene2D.OverlapCollider(col, _hits, _interactableLayers);

Unfortunately PhysicsScene (3D) doesn't have an equivalent method, rip :(
