Subject: [PATCH] fix webpack polyfills (#9735)
webpack polyfills did not work because useBuiltIns: 'entry' expects a
explicit core-js import. Changed it to 'usage' which does not require
these explicit imports and polyfills based on browserslist.
As a result, the built index.js now went from 128kB to 192kB.
