[Docs] improve rollup section of the bundling guide (#32440)

- rename `rollup.config.js` to `rollup.config.mjs` so it works regardless of the
consuming package's module type

- add a simpler configuration for packages that don't require polyfills/shims.

- change bundle output format from `iife` to `esm` format as latter should be
supported by recent browsers.
