Subject: [PATCH] Fix #8558: added ESM builds to fix 'require is not defined'
 via jsDelivr +esm

- Add an 'es' format output for every rollup entry (core, extensions,
  themes, locales), producing .esm.js / .esm.min.js files with a
  top-level 'import $ from "jquery"' that ESM pipelines can resolve
- Add 'module' field to package.json so ESM-aware resolvers (jsDelivr
  +esm, bundlers) pick the ESM build instead of converting the UMD one
