Do not autoplay swiper if not in view

[davidlj95]

Autoplay is enabled on all swipers. Which is unnecessary (JS compute time) if swipers aren't on screen. Unfortunately, there's no option in Swiper.js to just enable autoplay when swiper is visible

We could add something with Intersection Observer API to enable this.

Indeed the autoplay functionality seems doesn't use best practices, because Lighthouse is not happy with it. So if autoplay is just enabled for the swiper on screen, we could pass the check. Check started failing when we created the project detail view, which was the first page to contain more then one image swiper (just one project existed at the beginning)
