feat(kinesisanalytics-flink): add support for Flink 1.19 (#30723)

### Reason for this change

Amazon Kinesis Data Analytics now supports Apache Flink v1.18 ([LINK](https://aws.amazon.com/about-aws/whats-new/2024/06/amazon-managed-service-apache-flink-1-19/))

This is also supported in Cloudformation ([LINK](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-kinesisanalyticsv2-application.html#aws-resource-kinesisanalyticsv2-application-properties))

### Description of changes

- Added Flink 1.19 to `Runtime` type
- Updated Readme to reference Flink 1.19
