since we're not doing the disabled cursor thing anymore anyway, remove confusing/unnecessary mention for link-based disabled buttons
make the disabled toggle example using a link actually follow the preceding advice of also having tabindex="-1" and aria-disabled="true"
tweak the link functionality callout to also still mention aria-disabled to reinforce the idea
tweak toggle state description (not just <button>s, but also links etc...so just remove mention of <button> there; also reinforce accessibility aspect once more)
add a new callout that cross-references checkbox-based toggles, and what the similarity/difference between them is
add a matching cross-reference callout to the checkbox-based toggle buttons page
