Review Comment:
This breaks the build due to changes of #19781 - maybe we should correct the
type as follow:
```java
initializingTopics.put(topicId, new
InitMapValue(topic.topicName(), topic.partitions().stream()
.map(AlterShareGroupOffsetsRequestData.AlterShareGroupOffsetsRequestPartition::partitionIndex)
.filter(existingPartitions::contains)
.collect(Collectors.toSet()), curTimestamp));
```
