Change name of custom post type archive

The register_post_type has_archive option also accepts a string. That string will be used for the archives. See the changes in the code below:

function create_reviews_post_type() {
    register_post_type('acme_reviews', array(
        'labels' => array(
            'name' => __('Reviews'),
            'singular_name' => __('Review')
            ),
        'menu_position' => 5,
        'public' => true,
        'has_archive' => 'reviews',
    );
}
add_action('init', 'create_reviews_post_type');
