Testimonial Cards Displaying and Remove Unnessary Things

[harshpareshbhaigosalya]

This PR includes the following changes and fixes:

1. Navigation Bar Improvements:-

• Made the navigation bar transparent to blend with the overall theme.
• Fixed the navigation bar to the top, ensuring it remains visible even when scrolling down.

2. Removal of Redundant 'Go Back' Button:-

• Removed the unnecessary 'Go Back' button in the About section, as navigation to the Home page is already accessible through the navbar.

3. Testimonial Card Layout Update:-

• Updated the layout of the testimonial cards for a more modern and clean design. The changes include better spacing, alignment, and readability.

Additional Information:
These changes enhance the visual consistency of the website, reduce redundancy, and provide a smoother navigation experience.
