Quarkus: Add dependency to quarkus-jackson

The following change in Quarkus:

• https://github.com/quarkusio/quarkus/pull/21142

Caused the upgrade to 2.5.0.CR1 to fail

• https://github.com/kiegroup/kogito-runtimes/pull/1713

quarkus-jackson only bring pure "jackson-databind" plus interfaces for customization (i.e. ObjectMapperCustomizer), and it won't prevent mixing resteasy with JSON B support (that would be quarkus-resteasy-jackson, which remains optional)

so the proposed fix is to (temporarily?) depend on quarkus-jackson to avoid further breakage on 1.14. We can re-evaluate the choice as soon as 2.5.0 support is merged.
