[Bug]: Description of readBootstrapServerAndTopic parameter is incorrect

What happened?

The description for readBootstrapServerAndTopic includes this example string: localhost:9092;topic1,topic2, which implies the template can read from multiple source topics.

However from testing, this doesn't seem to work. I get the following error:

 org.apache.kafka.common.errors.InvalidTopicException: Topic 'topic1,topic2' is invalid
