Fix for the latest dependency changes

* Upgrade to the latest Jackson version
* Use Jackson 3 API in the `testcontainers-rabbitmq` since this is now a default in Spring Boot
* Fix `web-sockets` to implement `getComponentType()` on the custom `AbstractPayloadTransformer`
since that is a requirement now in Spring Integration
