Java2Swift: nested types in generic types

[ktoso]

For example trying to import guava 'com.google.guava:guava:33.3.1-jre' results in:

/Users/ktoso/code/swift-java/Samples/JavaDependencySampleApp/.build/plugins/outputs/javadependencysampleapp/JavaGuava/destination/Java2SwiftPlugin/generated/ImmutableList+Builder.swift:7:63: error: reference to generic type 'ImmutableList<E>.SubList.Builder' requires arguments in <...>

 7 |   open class Builder<E: AnyJavaObject>: ImmutableList.SubList.Builder {
