build(deps): bump i18next-http-backend from 3.0.6 to 4.0.0

[dependabot]

Bumps i18next-http-backend from 3.0.6 to 4.0.0.

Changelog

Sourced from i18next-http-backend's changelog.

4.0.0

• BREAKING: drop cross-fetch dependency. i18next-http-backend now requires a host-provided fetch. This is available in Node ≥ 18 (stable since Node 21), all modern browsers, Deno, and Bun. For runtimes without native fetch, install a ponyfill yourself and inject it via options.alternateFetch, or stay on v3.x.
• BREAKING: minimum Node version is now 18 (engines.node = ">=18").
• chore: simplified environment detection in lib/request.js — uses globalThis (with global / window fallbacks for legacy embedded runtimes) instead of separate global.* / window.* branches per API. XHR / ActiveXObject are still picked up if the host provides them, but no longer polyfilled.
• chore: declared "sideEffects": false for better tree-shaking by downstream bundlers.
• build: replaced babel + browserify + uglify-js with tsdown (rolldown + oxc). One config produces ESM, CJS, and the IIFE browser bundles. Drops @babel/cli, @babel/core, @babel/preset-env, babel-plugin-add-module-exports, browserify, uglify-js, the fixcjs rewrite hack, and the --ignore cross-fetch browserify flag. Side benefit: minified browser bundle shrinks from ~13 KB to ~6.8 KB (oxc minifier + no babel runtime helpers).
• build: ESM and CJS outputs are now bundled into a single index.js per format (previously one file per lib/*.js module). The package's exports map is unchanged, so this is invisible to consumers using documented entry points.
• lint: replaced eslint-config-standard (+ five plugins) with neostandard and migrated to ESLint 9 flat config (eslint.config.mjs). Removed deprecated tslint and dtslint — test:typescript now runs tsc --noEmit plus tsd.
• chore: tightened .npmignore — published tarball no longer includes the source lib/, the build configs (tsdown.config.ts, eslint.config.mjs, tsconfig.json), or the root index.js re-export shim. Drops from 21.3 KB → ~17 KB packed.
• docs: alternateFetch is now documented in the README options block as the supported escape hatch for fetch ponyfills, test mocking, and request interception. v4 migration note added to "Getting started".

Tested fine locally, and we are on a much newer node than the one affected by the breaking change. Waiting to see if maybe recreating after #1305 might remove the libc stuff being removed.
