Description

Update serverless-workflow-functions-events-quarkus example.

Issues

• [To be discussed] The structure could be updated. The installation should be placed before the application description.
• Building the application fails with:

  Failed to execute goal io.quarkus:quarkus-maven-plugin:3.8.4:generate-code (default) on project serverless-workflow-functions-events-quarkus: Quarkus code generation phase has failed: Failed to bootstrap application in NORMAL mode: Failed to inject extension deployment dependencies for org.kie.kogito.examples:serverless-workflow-functions-events-quarkus:1.0-SNAPSHOT: Failed to collect dependencies of org.drools:drools-quarkus-rules-deployment:jar:999-SNAPSHOT: either its POM could not be resolved from the available Maven repositories or the artifact does not have any dependencies while at least a dependency on the runtime artifact org.drools:drools-quarkus-rules:jar:999-SNAPSHOT is expected
  

• The example contain Kogito references:
  • rules
  • "Install the KogitoSource via command line."
    • [Investigate] Is it possible to replace this with anything?
  • "It will deploy the objects from knative.yml and kogito.yml generated files"

Acceptance criteria

All issues listed above are fixed.
The example is working properly and well documented in readme file.
