mq.tf instance type is deprecated

in sample-devops-agent-ecs-workshop\terraform\lib\dependencies\mq.tf (line 17)

```
instead of ...
host_instance_type = "mq.t3.micro"
use
host_instance_type = "mq.m5.large"
```

Refer: mq.**t3.micro is deprecated** [](https://docs.aws.amazon.com/amazon-mq/latest/developer-guide/rmq-broker-instance-types.html)

Important
The mq.t3.micro instance type is deprecated and is no longer available for new broker creation. Existing brokers using mq.t3.micro reach end of support on October 1, 2026. We recommend upgrading to mq.m5.large or mq.m7g.medium or higher before the end of support date to prevent disruptions.

You cannot downgrade a broker from an mq.m7g or mq.m5 instance type to a mq.t3.micro instance type.

The mq.t3.micro instance type does not support cluster deployment.

Ouvrez sample-devops-agent-ecs-workshop/terraform/lib/dependencies/mq.tf et examinez la ligne 17. Remplacez la valeur obsolète mq.t3.micro par le type d’instance pris en charge demandé, puis vérifiez que la configuration Terraform reflète toujours la référence AWS et qu’il ne reste aucune autre utilisation de mq.t3.micro.
