Application throws "Configuration validation failed" exception for service-binded properties
### Describe the bug

I have an application, which uses service binding and requires postgress, deployed by crunchydata operator. When I deploy the app on the Openshift via extension, it fails to start with "Configuration validation failed" exception, but only if use 999-SNAPOSHOT Quarkus build

### Expected behavior

The application should start successfully, same as for 3.1.0.Final and 3.2.0.Final

### Actual behavior

The pod crash-loops and logs contain this exception:
```

### How to Reproduce?

1.  Clone the reproducer `git clone  https://github.com/fedinskiy/reproducer -b postgres-cluster-properties`
2. Create new project on kubernetes: `oc new-project fd-postgres`
3. Verify, that Crunchy operator is installed:
```
$ oc get csv
NAME                              DISPLAY                           VERSION   REPLACES                          PHASE
datagrid-operator.v8.4.6          Data Grid                         8.4.6     datagrid-operator.v8.4.5          Succeeded
postgresoperator.v5.4.0           Crunchy Postgres for Kubernetes   5.4.0     postgresoperator.v5.3.0           Succeeded
serverless-operator.v1.29.0       Red Hat OpenShift Serverless      1.29.0    serverless-operator.v1.28.0       Succeeded
service-binding-operator.v1.3.3   Service Binding Operator          1.3.3     service-binding-operator.v1.3.1   Succeeded
```
4. Create postgres cluster: `oc apply -f pg-cluster.yml`
5.  Wait for cluster to start: `oc wait --for condition=Ready --timeout=300s pods --all`
6. Deploy the app: `mvn package -Dquarkus.kubernetes.deploy=true -Dquarkus.openshift.expose=true -Dquarkus.openshift.route.expose=true -Dquarkus.kubernetes-client.trust-certs=true -Dquarkus.openshift.build-strategy=docker -Dquarkus.openshift.base-jvm-image=registry.access.redhat.com/ubi8/openjdk-17:latest -Dquarkus.platform.version=999-SNAPSHOT -Dquarkus.platform.group-id=io.quarkus`
7. Check deployments:
```
$ oc get pods
NAME                      READY   STATUS             RESTARTS      AGE
hippo-backup-b8f9-mmmhq   0/1     Completed          0             3m5s
hippo-instance1-4nbf-0    4/4     Running            0             3m22s
hippo-repo-host-0         2/2     Running            0             3m22s
theapp-1-build            0/1     Completed          0             2m5s
theapp-1-deploy           0/1     Completed          0             48s
theapp-1-zq2q6            0/1     CrashLoopBackOff   2 (22s ago)   45s
```
8. Check logs: `oc logs theapp-1-zq2q6` (results above)
9. If started using command `mvn package -Dquarkus.kubernetes.deploy=true -Dquarkus.openshift.expose=true -Dquarkus.openshift.route.expose=true -Dquarkus.kubernetes-client.trust-certs=true -Dquarkus.openshift.build-strategy=docker -Dquarkus.openshift.base-jvm-image=registry.access.redhat.com/ubi8/openjdk-17:latest -Dquarkus.platform.version=3.2.0.Final` the application starts successfully.
