Fixes: #3310

👨‍💻 Description

What does this PR do?

This PR addresses the issue of text and button visibility in dark mode on the index.html page, specifically in the testimonial section. The text "Users sharing their experience" and navigation buttons like "next" and "previous" were hard to read in dark mode due to the lack of sufficient contrast between the text color and the dark background.

Changes made:

• Added a light text color (#e0e0e0) for the testimonial section heading and navigation buttons in dark mode to ensure better readability.
• The changes were applied to:
  • Text: Heading "Users sharing their experience"
  • Buttons: "Next" and "Previous" buttons

This improves the user experience by ensuring the content is legible in both light and dark modes.
