Add roles added in ARIA 1.2

[WilcoFiers]

WAi-ARIA 1.2 has added a few new roles. Those should be added to axe-core. These roles aren't likely to effect accessibility when they're not supported so I think it's safe to add these right away.

See the ariaRole standards docs for how to do this

Hey there! I'm trying to gain more experience with accessibility, and I'd love to work on this issue!

All yours. Let me know if you need anything.

PS. I find running the following script while in the WCAG 1.2 spec page helps seeing which ARIA attributes to add to the requiredAttrs and allowedAttrs properties by hiding any global ones:

const globalAttrs = Array.from(
    document.querySelectorAll('#global_states li')
  ).map(li => li.textContent.replace(/\s*\(.*\)/, ''));

  const globalRoleAttrs = Array.from(
    document.querySelectorAll('.role-inherited li, .role-properties li')
  ).filter(li => globalAttrs.includes(li.textContent.replace(/\s*\(.*\)/, '')))

  globalRoleAttrs.forEach(li => li.style.display = 'none');
