Manually change the quantity even if for single digit number

_On the web page we can increase or decrease the quantity by one, but when a single digit number is already there then we cannot completely upgrade to a new quantity_

For example, If product 2 has 4 quantities already in the cart and we want to change the quantities to 92 then we have to increase the quantity 5 times to make it 9 and then add 2. Is a lengthy process.

Instead of this, we could have added the feature of manually editing the quantity with the exception that quantities should not be less than or equal to 0.
