[hacep] Missing Dependency

When from hacep/source directory, a maven build is launched this is the outcome:

```
mvn clean package

[ERROR] Failed to execute goal on project sample-hacep-project-client: Could not resolve dependencies for project org.kie:sample-hacep-project-client:jar:7.26.0.Final-redhat-00005: Could not find artifact org.kie:openshift-kie-hacep:jar:7.26.0.Final-redhat-00005 in jboss-early-repository (https://maven.repository.redhat.com/earlyaccess/all/)
```

In fact, there is no artifact at this URL:
https://maven.repository.redhat.com/earlyaccess/all/org/kie/openshift-kie-hacep/7.26.0.Final-redhat-00005/openshift-kie-hacep-7.26.0.Final-redhat-00005.pom
