Examples: updated the example of dynamic-routing to utilize the App Router (#67684) This PR updates the dynamic-routing example to use the App Router. Here are the changes that have been made: - Renamed the "pages" folder to "app" folder. - Updated the routing for `/`, `/about`, `/post/[id]`, and `/post/[id]/[comment]` files to align with the App Router. - Added the layout.tsx file as part of the App Router. - updated package.json to use the latest version. cc @samcx Co-authored-by: Sam-Phillemon <sam.philemon@qed42.com>
