feat(pie-textarea): DSW-3900 Add aria prop

[KatarinaNeskovic]

Describe your changes (can list changeset entries if preferable)

This PR adds aria prop to the pie-textarea. Browser tests are added. Testing in Aperture was done locally. Existing draft Aperture PR wasn't updated with the prop change to avoid pushing changes for each prop test.
