Bug description

The ARIA gridcell role is added to the Day button, but that is an incorrect role for the button since it does not represent a cell in a grid – it is in fact a child of a cell. Accessibility tests using the component are failing.

Expected behaviour

The role for the button could be button or omitted at all since it's a HTM button component and the role for it is clear.

@gpbl for what its worth, aria-selected is also erroring as Critical with aXe. I'm having to destructure it out of the buttonProps and leave it as an unused variable to avoid the errors.

Waiting on a fix for this!

Reason this is taking so long is because it is a breaking change: changing the HTML structure will likely break tests selectors and styles.

I could finally make some progress with this in PR #2089 and will cut a mayor release for this fix. More details coming soon... thanks a lot for your patience!
