Soft body demo: Lowered impulses because of lowered default mass

Browse Source 
Since #116041, the default mass of a soft body is 1 kg for Jolt Physics (just like Godot Physics). The demos were tweaked with the previous default mass, which is 1 kg per vertex for a total mass of >4000 kg. This change reduces the applied impulses so that the demos behave sensibly again.
