Description
Micronaut 5 bumps Jackson to 3. Core keeps Jackson 2 available via `JacksonMapper` for plugins, which means custom (de)serializers must be duplicated for both versions.
Affected: anonymous `new JsonSerializer() {...}` registered on a `SimpleModule` in
`src/main/java/io/kestra/plugin/serdes/json/IonToJson.java` (ION timestamp handling for `IonToJson`).
Action: duplicate this serializer so it works against Jackson 2 (via `JacksonMapper`) in addition to Jackson 3.
Context: kestra-io/kestra#18138, kestra-io/kestra-ee#9908 (Micronaut 5 / Jackson 3 core bump).

Research direction
Open src/main/java/kestra/plugin/serdes/json/IonToJson.java and inspect the anonymous Timestamp serializer registered on the SimpleModule. Trace how JacksonMapper exposes Jackson 2 for plugins, then verify that the ION timestamp serializer works with both Jackson 3 and Jackson 2. Done means both versions support the same custom serialization behavior.
