Fix collisions between the ball and the pads

I disagree, I find this mechanic interesting, as it is controllable.
You can add effects like slicing to ball, and it adds more spice to the game.

And unless you want to change Godot's physics, you won't be able to do that with a rigid body 2D.

I corrected the issue by adding a minimum speed in the integrate_forces of the Ball if its velocity is lower than min_speed (=150 as preselected value) and strictly greater than 0 to avoid conflicts with the reset position.

You're able to modify that (There's always a way :))

In the end I agree that controlling the ball like that can add some challenge and some fun. So we should keep that. However we should tweak it so that the ball has a minimum speed. Otherwise the ball can be way too slow.
