(Amazon.CDK.AWS.EKS.CfnCluster): Documentation sample does not work as shown

### link to reference doc page

https://docs.aws.amazon.com/cdk/api/v1/dotnet/api/Amazon.CDK.AWS.EKS.CfnCluster.html

### Describe your issue?

.csproj

```

Exe
netcoreapp5

Major

```

EksCdkStack.cs

```
... boilerplate
CfnCluster cfnCluster = new CfnCluster(this, Constants.CLUSTER_PREFIX, new CfnClusterProps
{
ResourcesVpcConfig = new ResourcesVpcConfigProperty
{
SubnetIds = new[] { combinedSubnets },
EndpointPrivateAccess = isClusterPublic ? false : true,
EndpointPublicAccess = isClusterPublic ? true : false,
},
RoleArn = clusterAdmin.RoleArn,
Name = clusterName.ValueAsString,
Version = clusterVersion.ValueAsString
});
... boilerplate
```

Documentation clearly states that we can use 'ResourcesVpcConfig = new ResourcesVpcConfigProperty', but:

- not using ResourcesVpcConfigProperty, I receive the error (cool, as expected):

```
Unhandled exception. Amazon.JSII.Runtime.JsiiException: Missing required properties for aws-cdk-lib.aws_eks.CfnClusterProps: resourcesVpcConfig
```

- using ResourcesVpcConfigProperty, it shows me:

```
The type or namespace name 'ResourcesVpcConfigProperty' could not be found (are you missing a using directive or an assembly reference?
```

- using ResourcesVpcConfig, it shows me:

```
The type or namespace name 'ResourcesVpcConfig' could not be found (are you missing a using directive or an assembly reference?
```

Start with the linked CfnCluster reference page and the shown .csproj and EksCdkStack.cs files, then reproduce the missing-type errors with Amazon.CDK.Lib 2.17.0. Compare the documented C# sample with the API exposed by that package; done means the sample uses an available type and compiles as documented.
