Added Scroll-Up Button for Improved Navigation on the About Page

[ak-0283]

As a contributor to GirlScript Summer of Code 2024, I noticed the absence of a scroll-up button on the Start Writing page, which made navigation challenging, especially on longer posts. To enhance user experience and streamline content creation, I implemented a scroll-up button, allowing users to quickly return to the top of the page. This feature improves accessibility and usability, making the page more intuitive and user-friendly.
