Update flink-connector-kinesis to any version equal to or newer than 1.15.2

[aholen]

Following the tutorial on https://catalog.us-east-1.prod.workshops.aws/workshops/63069e26-921c-4ce1-9cc7-dd882ff62575/en-US/lab7 - the step for configuring/updating TaxifareKDA results in the following error:

An unsupported Kinesis connector version has been detected in the application. Please update flink-connector-kinesis to any version equal to or newer than 1.15.2. For more information refer to connector fix: https://issues.apache.org/jira/browse/FLINK-23528
because of https://docs.aws.amazon.com/kinesisanalytics/latest/java/troubleshooting-unsupported-kinesis-connectors.html

Compiling the jar manually isn't trivial since https://mvnrepository.com/artifact/org.apache.flink/flink-connector-kinesis_2.11/1.15.2 doesn't exist.
