ReactDOM.render is no longer supported in React 18. Use createRoot instead.

Tests are warning us that we are using a deprecated feature. It can be seen in this build:
https://github.com/bjerkio/oidc-react/runs/7359386639?check_suite_focus=true

The full warning is this:

Warning: ReactDOM.render is no longer supported in React 18. Use createRoot instead. Until you switch to the new API, your app will behave as if it's running React 17. Learn more: https://reactjs.org/link/switch-to-createroot

Seems like we have a few references to this in our tests, so if anyone wants to open a pull request fixing that it would be awesome!

I would love to do that.
However , I can't seem to find the file where ReactDOM.render is called. Can you help me out please.

If you open the step (collapsible) named Run yarn test, there should be some more details there.

PS: Currently on my mobile phone, so I couldn't verify 😅
