When some module uses node builtins, rollup generates warning like this:
Rollup: "Creating a browser bundle that depends on Node.js built-in module ('util'). You might need to include https://github.com/ionic-team/rollup-plugin-node-polyfills"
Plugin rollup-plugin-node-polyfills is not updated two years, and has critical bug: ionic-team/rollup-plugin-node-polyfills#25
There is good maintained alternative rollup-plugin-node-builtins, that does not produces a bug. We should replace reference in warning.
