fix: handle non-existing getImages method in Carousel class

This commit addresses the issue where a call to the undefined method getImages on the possible false in Carousel.php was causing an error. A check is now in place before calling the method. Consequently, the phpstan-baseline.neon file has also been updated to remove the now unnecessary error suppression.
