+     * @description The Unpublish taxonomy call initiates a job to unpublish a taxonomy and/or specific terms from the specified environments and locales.
+     * @memberof Taxonomy
+     * @func unpublish
+     * @param {Object} data - Unpublish details (same shape as publish: locales, environments, items, etc.)
+     * @param {string} [api_version=''] - Optional API version (e.g., '3.2')
+     * @param {Object=} params - Optional query parameters. If params.branch is set, it is sent as the branch request header.
+     * @returns {Promise<Object>} Response object with unpublish job details
+     * @example
+     * import * as contentstack from '@contentstack/management'
+     * const client = contentstack.client()
+     *
+     * const unpublishData = {
