Accessibility in React Toolbar component

The Toolbar component has been designed, keeping in mind the WAI-ARIA specifications, and applying the WAI-ARIA roles, states, and properties along with keyboard support for people who use assistive devices. WAI-ARIA accessibility support is achieved through attributes like aria-orientation, aria-disabled, and aria-haspopup. It provides information about elements in a document for assistive technology. The component implements keyboard navigation support by following the WAI-ARIA practices, and has been tested in major screen readers.
