(servicecatalog): ProductStackHistory changes last product version ID

### Describe the bug

`ProductStackHistory` is expected to keep older product versions as-is for consistency. But currently, the ID of last deployed product version changes by adding new version.
This becomes a blocker for users of Account Factory Customization (AFC) in AWS Control Tower because users may lost product version id that is used by AFC blueprint.

### Expected Behavior

Product version IDs should be immutable when adding a new version with `currentVersionLocked: true`.

### Current Behavior

The ID of last deployed product version changes by adding new version.

### Reproduction Steps

## Deploy v1

```typescript
import { App, Stack } from 'aws-cdk-lib';
import { CloudFormationProduct, ProductStack, ProductStackHistory } from 'aws-cdk-lib/aws-servicecatalog';
import { Construct } from 'constructs';
import { Queue } from 'aws-cdk-lib/aws-sqs';

const app = new App();
const stack = new Stack(app, "ServiceCatalog")

class MyProduct extends ProductStack {
constructor(scope: Construct, id: string) {
super(scope, id);
new Queue(this, "SCQueue1")
}
}

const productStackHistory = new ProductStackHistory(stack, 'ProductStackHistory', {
productStack: new MyProduct(stack, 'MyProduct'),
currentVersionName: 'v1',
currentVersionLocked: true,
});

new CloudFormationProduct(stack, 'Product', {
productName: 'MyProduct',
owner: 'Platform team at Example Company',
productVersions: [
productStackHistory.currentVersion(),
],
});
```


## Deploy v2 with no changes in ProductStack

Start with the ProductStackHistory behavior shown in the TypeScript v1–v3 reproduction and compare the generated cdk diff and deployment results. Trace how currentVersionLocked and versionFromSnapshot determine product version IDs; done means adding a new version without changing the ID of the previously deployed version.
