feat: add enabled prop in StaggerProps

[OsamaAburabie]

Description:
This pull request introduces a valuable enhancement to the Stagger component. We have added a new enabled prop, which allows users to control the behavior of staggered animations. When enabled is set to true, the staggered animations will be applied as usual. However, when set to false, the animations will be disabled, and all child components will be rendered without any animation.

Motivation:
The addition of the enabled prop provides greater flexibility and control to developers using the Stagger component. It allows them to easily toggle the staggered animations on and off based on their specific application requirements. This feature can be particularly useful in scenarios where dynamic animation control is needed, enhancing the overall user experience.

Usage:
To disable staggered animations and render child components without animations, simply set the enabled prop to false when using the Stagger component.

<Stagger enabled={false}>
  {/* Child components */}
</Stagger>

By default, enabled is set to true, ensuring that the existing behavior of staggered animations remains unchanged.
