LPS-49177 - default-web-content-hook Carousel display issues

Hi Jon,

Attached is an update for https://issues.liferay.com/browse/LPS-49177.

These changes update the markup to now work with the updated carousel.

I must have forgotten to send this fix when I sent the fix for the image-viewer/carousel.  Sorry about that.

Please let me know if there are any issues.

Thanks!
