[feat]: add slow back animation prop for better ux

[Aberratio]

The animation of the card's return (animateBack) is very fast and makes a very "aggressive" movement of passing to the other side.

In order to make it possible to use a slower or even remove it altogether, I propose to introduce backAnimationType props that defaults to standard and keeps the existing operation.

On the other hand, it will be possible to use this function and:

• set the props to slow, which will delay the animateBack effect.
• set the props to none, which will completely remove the effect of the return animation.

This could be more readable.

      if (backAnimationType === 'standard') return physics.animateBack;
      if (backAnimationType === 'slow') return physics.animateSlow;
      return physics.none;

I think a much better solution to this is exposing the spring configuration for the back animation instead. Letting the user fine tune exactly how they want the back animation to behave.
