AWS CDK AWS IoT Alpha Constructs

The `aws-cdk-aws-iot-alpha` library provides experimental, higher-level (L2/L3) constructs for defining AWS IoT Core resources using the AWS Cloud Development Kit (CDK). As an 'alpha' module, its APIs are under active development and subject to non-backward compatible changes or removal in any future version. It allows developers to programmatically define IoT rules, logging, scheduled audits, and more, leveraging familiar programming languages. The current version is `2.250.0a0`, released as part of the AWS CDK v2 alpha series, with breaking changes announced in release notes rather than adhering to strict semantic versioning.
