DynamoDB: Validation error on Metric create

### Describe the bug

Using the .NET CDK, I am trying to create an Alarm on the MetricSuccessfulRequestLatency for our Dynamo table.

Regardless of the different attempts used, It seems to always trigger the following error.

> System.Exception: ValidationError: `Operation` dimension must be passed for the `SuccessfulRequestLatency` metric

From the new TableV2 instance

> conversationsTable.MetricSuccessfulRequestLatency(); seems to cause the issue.

I've tried
> conversationsTable.MetricSuccessfulRequestLatency(new OperationsMetricOptions())
> conversationsTable.MetricSuccessfulRequestLatency(new SystemErrorsForOperationsMetricOptions())
and populating the operations array with one or more operations.

There is no "Operation" property to set.

Start by running the supplied .NET reproduction with aws-cdk-lib 2.201.0 and inspect the implementation of MetricSuccessfulRequestLatency and its metric option types. Trace how the SuccessfulRequestLatency dimensions are assembled, then verify with cdk diff that the metric is created without the missing Operation validation error.
