3. When .NET Aspire 9 ships, we can "swap" the dependencies around.
   - The Aspire.RabbitMQ.Client package will be updated to depend on version 7 of RabbitMQ.Client.
   - If RabbitMQ.Client v6 is still in support, we can create Aspire.RabbitMQ.Client.v6 which has the dependency limit [6.8.1, 7.0.0) and works with the version 6 of RabbitMQ.Client.
   - Aspire.RabbitMQ.Client.v7 will be dead-ended. We won't make new .NET Aspire 9 versions of this package.

We never did this for Aspire 9. But we should do it for 13 now.

The same goes for MongoDB.Driver and v3. See #6380
