Update AriaRole type to WAI-ARIA 1.2

[webschik]

Hello,

I have a problem with AriaRole type.
It includes a list of all WAI-ARIA 1.1 role definitions which makes it impossible to use a meter role for the HTML element without workarounds like type casting.

Is it possible to update AriaRole and use a list of roles from WAI-ARIA 1.2?

Thanks for providing the docs, really helped ensuring all were added.

Looks like we were missing a few 1.1 roles too

Thanks for fixing this so fast!
