Document: Deploy a .NET Aspire project to Azure Container Apps using the Azure Developer CLI (in-depth guide)

Describe the issue or suggestion
Issue description:
After updating the Program.cs file in the AppHost project. "AddPostgres" missing reference.

• Deploy infrastructure updates

'IDistributedApplicationBuilder' does not contain a definition for 'AddPostgres' and no accessible extension method 'AddPostgres' accepting a first argument of type 'IDistributedApplicationBuilder' could be found (are you missing a using directive or an assembly reference?)

Suggestion:
Before replacing the code for Deploy infrastructure updates, you should download "Aspire.Hosting.PostgreSQL" first.
