i18next Fetch Backend

v7.0.0: A backend plugin for i18next that loads translation resources using the browser's Fetch API, suitable for modern browsers and Service Worker contexts. The package ships TypeScript types and requires Node >=20. It replaces XMLHttpRequest-based backends, offering native promise support and compatibility with fetch options like CORS and credentials. Release cadence is irregular; the latest major version removed deprecated callback-based fetch in favor of a function returning a Promise.
