[REF] website: rename slide method of CarouselItem option class

This method name, while being not specific enough to ease grepping,
leads to have `data-slide` in the option XML declaration. This was
actually confusing with the BS4 data-slide of carousel elements. Here,
in master, this leads to even more confusion as BS5 uses data-bs-slide
thus making it unsure if the option's `data-slide` has to be converted
or not during the current BS5 bug fixing.

Indeed, it was converted by mistake with the original BS5 merge at [1]
and later fixed with [2] but it could be matched by regexes again and
be re-broken by mistake.
