intl-numberformat is using named exports from JSON modules (webpack5 incompatibility)

[sppatel]

Which package?
intl-numberformat

Describe the bug
Webpack 5 throws a warning if it encounters any named exports from JSON files as described in the webpack 5 migration guide.

https://webpack.js.org/migrate/5/#cleanup-the-code

Using named exports from JSON modules: this is not supported by the new specification and you will get a warning. Instead of import { version } from './package.json'; console.log(version); use import package from './package.json'; console.log(package.version)

To Reproduce
Steps to reproduce the behavior:

1. Go to

   formatjs/packages/intl-numberformat/src/core.ts

   Line 13 in 028e1e5

   import {names as numberingSystemNames} from './data/numbering-systems.json';

2. The import here is not supported by the new specification as indicated above.
