[FEAT]: Add Hover effect on links in testimonial section

[Mayank233444]

Description

In the testimonials section there is no clear identification of where to click on the testimonial card to redirect to the course link.

To Reproduce

1. Open the website and scroll down.
2. Observe the testimonials section and locate different testimonial cards.

Expected Solution

Adding hover effect on a testimonial card and redirecting to course link after clicking it will look better.

Alternative solution

Adding hover feature only to the course name written in green colour on the testimonial card will also look better.
