Enhance Cart Quantity Update Functionality for Improved User Experience

[ChoaibMouhrach]

When adding an item to the cart and attempting to update its quantity, the system lacks debounce functionality. This means users must adjust the quantity one by one, which creates a suboptimal user experience.

I would like to contribute a solution to this issue through a pull request. Please consider assigning it to me if that works for you.
