build: Ensure compatibility with newer Java versions

Java changed the way how it processes annotations:

```
As of JDK 23, annotation processing is only run with some explicit configuration of annotation processing or with an explicit request to run annotation processing on the javac command line.
```

this messes with lombok, this compiler configuration will change the default behavior, so it works with java 23
