Bug Description

The segmented button's ul HTML element with role "listbox" has two issues regarding aria attributes:

1. Remove aria-multiselectable="true" for selectionMode="Single" — When selectionMode="Single" is configured, only one segment can be selected at a time. In this case, the segmented button should not be declared as multiselectable.
2. Add aria-orientation="horizontal" — The segmented button is oriented horizontally. However, due to the "listbox" role, the default orientation is set to vertical.
