Improve the local development story with the Azure Service Bus emulator

[danielmarbach]

Microsoft created an emulator allowing the use of Azure Service Bus without a namespace for local development and testing purposes.

• Microsft Artifact Registry: https://mcr.microsoft.com/en-us/artifact/mar/azure-messaging/servicebus-emulator/about

For instance, using Testcontainers, Docker Compose or Aspire, the emulator can be dynamically configured and managed per sample similar to how we already support local exploration of samples with SQL Server and other technologies that have container support.

Samples could leverage the emulator for faster exploration, offering an alternative to the cloud-based approach.
