`SnakeCaseStrategy` produces duplicated json

### Expected Behavior

Serialization as usual
as with

### Actual Behaviour

or with native annotation

other strategy works fine for some reason

### Steps To Reproduce

I tried to reproduce with Spok in `JsonNamingSpec.groovy` but couldn't.
I guess it's again some strange combo of dependencies, or something else.
No custom mapper, Serde, no configuration in application.yml nothing special about the setup. Maybe it's a regression in RC-x versions. Not sure.
Pojo is primitive.
```java
@Value
@Builder(toBuilder = true)
class Pojo {
UUID uuid;
Instant timestamp;
}
```

### Environment Information

Serde RC-2
Java 11

### Example Application

_No response_

### Version

3.3.3

Start by reviewing the existing JsonNamingSpec.groovy reproduction attempt and compare SnakeCaseStrategy with the native annotation and another naming strategy under Java 11 and Serde RC-2. A useful outcome is a focused reproduction or regression test showing whether serialization emits duplicated JSON; the issue currently provides no example application or confirmed failing setup.
