[BUG] Fix Dark Theme of About Page

[Adi-204]

Bug Description: In the dark theme of the website, the content in the "About" section is not visible due to poor contrast between the text and the background. The text appears very faint and difficult to read. Other pages in the dark theme seem to have better contrast, but the "About" page is inconsistent, making it harder for users to read the information.

How to Fix It:
Apply Uniform Styling: Ensure that the dark theme styling is applied consistently across all pages. Modify CSS of About page.
