[Proposal] Addition of ARIA to the accessibilityFeatures list of values

Hello everyone,
As we make improvement on the "Schema.org Accessibility Properties for Discoverability Vocabulary"<https://www.w3.org/2021/a11y-discov-vocab/latest/>

I would like to propose including "ARIA" to the accessibilityFeatures list of values.
Currently we have this under the accessibilityAPI with a definition of:

2.2.2 ARIA: Indicates the resource uses ARIA markup to improve interoperability with platform APIs.

I propose to move "ARIA" from accessibilityAPI to accessibilityFeature instead as I don't feel this makes sense as an accessibilityAPI.

Please respond by March 1, 2022 16:00 UTC if you have any concerns over this proposed change.

Thank You
