Upgrade to Amplify Version 6

[bpauwels]

The example react-app in this repository uses version 5 of the amplify libraries. If you try to use the code in your own project npm installs amplify v6 by default, in which the imports have changed.

See aws-amplify/amplify-js#12594

Looking forward it would be nice to have this updated here.

True!

If you've figured out the V6 config please paste it here to help others. Thanks!

Just figured it out, will create a PR for this.
