fixes #1303

We have Top & Bottom buttons on the armadaproject.io website which will redirect you directly to the top of the page or bottom of the page where you are not able to experience scrolling behavior bcz it's just too quick and rough. I made an enhancement to those buttons to enable smooth scrolling for the whole page. you can check both the Top & and Bottom buttons behavior by clicking on them and you can feel the experience. I found this more specific to user experience enhancement

giving a screenshot where you can see top and bottom buttons on the bottom left and bottom right side of the page.
