(aws-stepfunctions-tasks): Add support for Kinesis getShardIterator and getRecords actions

### Describe the feature

Step Functions support `arn:aws:states:::aws-sdk:kinesis:getShardIterator` and `arn:aws:states:::aws-sdk:kinesis:getRecords` resource types now. Please add CDK support for it.

### Use Case

I would like to be able to use L2 CDK constructs for Kinesis tasks in Step Functions

### Proposed Solution

_No response_

### Other Information

_No response_

### Acknowledgements

- [ ] I may be able to implement this feature request
- [ ] This feature might incur a breaking change

### CDK version used

2.59.0

### Environment details (OS name and version, etc.)

Ubuntu 20

Start in the aws-stepfunctions-tasks area by locating the existing L2 Kinesis task support and how Step Functions AWS SDK actions are represented. Compare the existing action patterns, then add support for getShardIterator and getRecords and verify both resource types can be used through L2 constructs.
