[Select]: a11y collapsed Select does not have the role of collpased

[AlexYanSap]

Bug Description

It's an incident from the customer that the collapsed select should have the role of the collapsed as recommended by the https://www.w3.org/WAI/WCAG21/Understanding/name-role-value.

I noticed the SR did announce the collapsed state even though we have not set the role as recommended.
