• Fixes [Feature] Add a scroll back to top button #168 by @Riddhi9570

Description

In response to issue 168, a "go to top" button has been implemented with meticulous attention to detail. The button seamlessly integrates with the website's theme through precise color matching and styling. Moreover, to enhance user experience, a subtle yet engaging scale animation has been incorporated, triggered upon hovering over the button. This enhancement not only addresses the specific issue but also adds a touch of interactivity, elevating the overall usability of the website.
