Description

The v9 Spinner does not have an aria-label nor aria-live for the spinner and does not have any suggestions for consumers using the v8 with these props on how to migrate, thus the doc is incomplete.

@snisonoffMS Is there an issue with aria-label not being applied to the v9 Spinner?

I tried it in a stackblitz and it appears to work correctly: https://stackblitz.com/edit/epecwzke?file=src%2Fexample.tsx

@CampbellOwen You seem to be confusing this issue with #33841 - feel free to close that one because I talked to Sarah about it and it turned out my expected behavior was wrong.

This bug is for the Migration Docs, the fact that the docs imply that the aria-label is gone, when it is not.
