Carousel navigation arrows remain clickable when no additional content is available

[ravichudasama01]

In the Style Variations carousel, the navigation arrows remain active and clickable even when there is no more content available in the respective direction. This occurs at both the beginning (previous/left arrow) and the end (next/right arrow) of the carousel.

Steps to Reproduce:

Open the theme page (Example : ​https://wordpress.org/themes/salecraft-ecommerce/).
Scroll to the Style Variations section.
Navigate to the first item and observe the previous (left) arrow.
Navigate to the last item and observe the next (right) arrow.

Actual Result:
The navigation arrows remain enabled and clickable even when there is no additional content to navigate to.

Expected Result:
The previous (left) arrow should be disabled or hidden at the beginning of the carousel, and the next (right) arrow should be disabled or hidden at the end of the carousel when no further content is available.
