/**
 * Returns a client info tag string for Redis client identification.
 *
 * This function reads the version from `@fortedigital/nextjs-cache-handler/package.json`
 * and returns a formatted string like `nextjs-cache-handler_v2.5.1`.
 *
 * If the version cannot be read, it falls back to `nextjs-cache-handler`.
 *
 * @example
 * ```js
 * import { createClient } from 'redis';
 * import { getClientInfoTag } from '@fortedigital/nextjs-cache-handler/helpers/getClientInfoTag';
 *
 * const client = createClient({
 *   url: 'redis://localhost:6379',
 *   clientInfoTag: getClientInfoTag(),
 * });
 * ```
 *
 * @returns The client info tag string for Redis identification.
