Update Remix template version for Delivery Customizations sample app

[Shaffan]

An ATC request has been raised here noting that this tutorial is broken.

After some investigation I found that the remix version for the sample app is out of date, and some of the packages have moved.

This PR updates the Delivery Customizations sample app to use the latest version of the Remix app template.
