feat(msk-alpha): new KafkaVersions 3_7_X and 3_7_X_KRAFT

[nmussy]

Issue # (if applicable)

None

Reason for this change

Update the CDK listed Kafka versions to match the current availability, as well as add missing deprecated versions

Description of changes

Even though there is a Metadata mode input in the web console (see announcement), there doesn't seem to be any associated fields, and the metadata mode is only dictated by the selected version according to the docs:

To create a cluster in KRaft mode using the MSK API CreateCluster or CreateClusterV2 operations, you should use 3.7.x.kraft as the version. Use 3.7.x as the version to create a cluster in ZooKeeper mode.

Given this, I don't see a reason to add a field to the KafkaVersion class to differentiate between the ZooKeeper and KRaft mode. This may easily be added in the future if needed.

I've also refactored the tiered array to increase maintainability and align it with other version classes, such as the RDS EngineVersions. See docs for supported versions:

The Amazon MSK cluster with tiered storage enabled must use version 3.6.0 or higher, or 2.8.2.tiered.

I don't think it's worth parsing the version to automatically determine the tiered storage support, as we already have non-semver versions and support may be dropped for future versions.

Description of how you validated changes

I compared the current CDK versions to live SDK data, using the kafka:ListKafkaVersions API results, and updated the cluster version integration
