reconcile WCAG Tutorial Carousel with WAI ARIA Practices Carousel

[DavidMacDonald]

I'd like to see a reconciliation between the tutorial carousel and the aria-practices carousel.
Perhaps a discussion between the ARIA practices group and @yatil .

https://www.w3.org/TR/wai-aria-practices-1.1/examples/carousel/carousel-1.html
https://www.w3.org/WAI/tutorials/carousels/

the tutorial is a few years old and perhaps Education and Outreach could update it, or propose amendments to aria practices where appropriate.

I've filed an issue with the WCAG tutorial also.
w3c/wai-tutorials#594

I'd like to see a united approach across WAI groups where possible.
