Add to official docs (or at least to the AZD repo's doc) the strategies AZD uses for provisioning and deploying Azure Container Apps.

This documentation should help AI-models to follow some steps to implement it.

Strategies:

• container-app-upsert (seen in todo-templates and composability)
• delay-deployment (used by .NET Aspire)

Customers should be able to understand as well how to implement and make this work.
