Support for multiple applications in a monorepo. The template already supports multiple applications but the support is kind of rough around the edges and not everything works completely smoothly. It requires project teams to do manual changes like rename app to the name of their application, and things like update-template.s don't work with renamed applications. Moreover, there aren't any built-in instructions to do this, so project teams kind of have to figure it out on their own.

This feature would provide out of the box functionality for:

• renaming the application from "app" as part of the template installation step. the functionality would also update other files like .github/workflows/cd-app.yml, etc.
• enhance the update template script to be able to update the infra template for project teams that renamed their "app" and for project teams that have multiple applications — the update template script would update all of the applications seamlessly
