docs(metrics): note that CloudWatch needs hudi-aws-bundle on Spark (#19473)
The CloudWatch reporter ships in the optional hudi-aws module, which
hudi-spark-bundle does not shade (hudi-flink-bundle and
hudi-kafka-connect-bundle do). Setting the reporter type to CLOUDWATCH on a
Spark bundle therefore fails to load the reporter class, which is the
complaint in apache/hudi#15293. apache/hudi#19418 makes that failure
actionable; this stops users from reaching it in the first place.
Applied to next and to version-1.2.0, the current released docs.
Closes #19472.
