Issue Description

The registry-viewer does not support dynamic routing atm. A nice feature would be to add this support to the viewer so it can support new stacks added to the registry.

From a quick research around the issue, I've noticed that next.js includes this functionality (see: https://nextjs.org/docs/pages/building-your-application/routing/dynamic-routes)

Acceptance Criteria

• The registry-viewer is able to serve automatically new pages that have been generated after an index.json file update.
