Describe the bug

There's an inconsistency in the AWS CDK Kinesis event source mapping validation. According to the documentation, -1 is the default value for retryAttempts which should set retries to infinite. However, when explicitly setting this value to -1, validation fails with:

ValidationError: retryAttempts must be between 0 and 10000 inclusive, got -1
  at path [X] in aws-cdk-lib.aws_lambda.EventSourceMapping

Documentation Reference

Steps to Reproduce

new KinesisEventSource(telemetryStream, {
  startingPosition: StartingPosition.LATEST,
  batchSize: 10000,
  maxBatchingWindow: Duration.seconds(30),
  parallelizationFactor: 1,
  retryAttempts: -1, // This fails validation
  reportBatchItemFailures: false,
  bisectBatchOnError: false
});

Expected Behavior

Since -1 is documented as the default value that sets retries to infinite, it should be accepted by the validation.

Actual Behavior

Validation fails with: retryAttempts must be between 0 and 10000 inclusive, got -1

Workaround

The only current workaround is to omit the retryAttempts property entirely to use the default, or set it to a value between 0 and 10000.
