[Bug]: Unable to connect to GMK topic using Kafka-client 4.0.0

### What happened?

I tried running a Dataflow job that reads messages from a Kafka topic using kafka-client 4.0.0 and my reads were silently failing. Downgrading to 3.7.0 caused reads to succeed.

When I created my Kafka Read DoFn I specify [withGcpApplicationDefaultCredentials](https://github.com/apache/beam/blob/40e2b0d01f26c20f792897638600bf162905252c/sdks/java/io/kafka/src/main/java/org/apache/beam/sdk/io/kafka/KafkaIO.java#L1555)

I'm currently running beam version 2.70.0-snapshot
