Rename the container apps

When you look at the best [naming practices](https://learn.microsoft.com/en-us/azure/cloud-adoption-framework/ready/azure-best-practices/resource-abbreviations#containers), it is recommended to prefix a container app with `ctap`. So we should rename our apps:

```
QUARKUS_APP="ctap-quarkus"
MICRONAUT_APP="ctap-micronaut"
SPRING_APP="ctap-springboot"
```

Instead of

```
QUARKUS_APP="quarkus-app"
MICRONAUT_APP="micronaut-app"
SPRING_APP="springboot-app"
```

We should check the [Azure Naming Tool](https://github.com/microsoft/CloudAdoptionFramework/tree/master/ready/AzNamingTool).
