bug: Cannot implement Kotlin interface DgsReactiveCustomContextBuilderWithRequest in Java

[petrmac]

Please read our contributor guide before
creating an issue.

Expected behavior

Interface should be possible to implement

Actual behavior

When trying to implement the interface in Java project, the interface is not visible:

error: cannot find symbol
public class CredentialsContextBuilder implements DgsReactiveCustomContextBuilderWithRequest<CredentialsContext> {
                                                  ^
  symbol: class DgsReactiveCustomContextBuilderWithRequest

Steps to reproduce

Implement the interface in Java project (not Kotlin).
Using the version: graphql-dgs-reactive-9.1.0.jar

Initially was using:
implementation "com.netflix.graphql.dgs:graphql-dgs-webflux-starter"
but now migrated to the newly endorsed
implementation "com.netflix.graphql.dgs:graphql-dgs-spring-graphql-starter"

Any help would be greatly appreciated!
