VehicleEntityCollisionEvent fired with VehicleBlockCollisionEvent

Expected behavior

The VehicleEntityCollisionEvent should only be triggered if the event parameter is a VehicleEntityCollisionEvent.

Observed/Actual behavior

The VehicleEntityCollisionEvent gets triggered with a VehicleBlockCollisionEvent as event parameter.

Steps/models to reproduce

    @EventHandler
    public void onVehicleCollision(VehicleEntityCollisionEvent event) {
        plugin.getLogger().info("Vehicle collision event triggered with " + event.getClass().getName());
    }

Start by reproducing the issue with the provided CollisionExample handler on Paper 1.20.6-147, then read the VehicleEntityCollisionEvent and VehicleBlockCollisionEvent definitions and their event-dispatch path. Done means the handler receives only VehicleEntityCollisionEvent instances and block collisions no longer trigger it.
