/**
 * Checks whether the explicit `role` attribute value is permitted on the element

 *
 * Each HTML element defines a set of roles that may be assigned to it. Some elements
 * (e.g., `<meta>`) do not allow any role overrides. This checker enforces those constraints.
 *
 * @param attr - The `role` attribute node to inspect.
 * @returns A violation if the role is not in the element's list of permitted roles.
