Allow to configure custom Hibernate user types for Quarkus outbox extension

Hello,

I am unable to find a way to store payload as jsonb in outbox table.

I have tried to define a custom converter and defined it here quarkus.debezium-outbox.payload.converter with no luck.+

Could you update this sample (or add another one) https://github.com/debezium/debezium-examples/blob/master/outbox/order-service/src/main/resources/application.properties with a full jsonb support for payload data.

It seems that a custom AttributeConverter for a Postgres jsonb column is not supported. Hence a Type should be used instead likes it was done here : https://github.com/Naros/debezium-quarkus/blob/master/extensions/outbox/runtime/src/main/java/io/debezium/quarkus/outbox/OutboxEvent.java#L49

(using hibernate-type-52).

Regards,

Damien
