Webpack5: Addons throw error on start

Describe the bug After updating to use the webpack5 builder with Storybook 6.2.0-beta.1 running storybook-start builds successfully but after opening the tab, there is a loading spinner with error.

Uncaught (in promise) RangeError: Maximum call stack size exceeded
    at Object.exports.deprecate (vendors-node_modules_storybook_addon-a11y_dist_esm_register_js-node_modules_storybook_addon-a-4deea9.b4c677ad3a67aca938fd.bundle.js:126199)

Seems to also happen from the other addons when I start disabling some.

To Reproduce Steps to reproduce the behavior:

1. Use Webpack5 builder (followed this example repo)
2. Run storybook-start
3. Notice error in the console

Expected behavior Addons work as expected.

Awesome. I bet that was it! Closing this for now.

@shilman Not sure what changed (perhaps the ESM file-loader fix?) but upgrading from 6.2.0-rc.3 to 6.2.3 seems to fix things and this snippet now works as expected:

import pkg from '../packages/core/package.json';

const DS_TITLE = `Design System ${pkg.version}`;

export default DS_TITLE;
