Modifying the cart should reset the checkout step and go back to first step instead of skipping

Proposed Solution:
1. Provide a config in checkout flow for this.
2. or Check if there is any necessity to go to first step by analysing the product added to cart and see if there's any reason for resetting the step to first.

Just for anyone looking for it before patch arrives.
one suggested way is to

React to any of the cart events and then set preferred value as below
$cart->checkout_step->value = 'your_step'
