redshift-alpha: Create cluster from snapshot

### Describe the feature

One of the reasons we are not using the `aws-redshift-alpha` and stick to the stable library is because we haven't found a way to create a cluster in Redshift using a snapshot. The construct `CfnCluster` receives the parameter `snapshotIdentifier`, while the construct `Cluster` from the module alpha doesn't have any parameters to do so.

Is there any intention of including this on the alpha module? We would be very interested in creating the logic schemas (tables, users, etc) through CDK but found this blocker.

### Use Case

Be able to create a cluster in Redshift through CDK from a snapshot, for aws-redshift-alpha

### Acknowledgements

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

### CDK version used

2.147.3

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

macOS Sequoia version 15.2

Start with the aws-redshift-alpha Cluster construct and compare its options with the CfnCluster snapshotIdentifier parameter described in the issue. Inspect the construct's existing tests or synthesized-template coverage, then verify that creating a cluster from a snapshot produces the expected Redshift configuration.
