EKS: `LaunchTemplateSpotOptions` are not supported while create=ing EKS Managed Node Groups with a Launch Template.

### Describe the bug

Trying to create an EKS Managed Node Group with a Launch Template using CDK EKS/EC2 module with following spot options.

const launchTemplateSpotOptions: ec2.LaunchTemplateSpotOptions = {
blockDuration: cdk.Duration.hours(1),
interruptionBehavior: ec2.SpotInstanceInterruption.STOP,
maxPrice: 10,
requestType: ec2.SpotRequestType.ONE_TIME,
validUntil: cdk.Expiration.after(cdk.Duration.days(90))
};

EKS Managed Nodegroup creation fails with following error :

```
7:02:50 PM | CREATE_FAILED | AWS::EKS::Nodegroup | blueprintconstruct...templatengECF74DC1
Resource handler returned message: "Instance market options are not supported with the launch template. (Service: Eks, St
atus Code: 400, Request ID: 2bc085ab-99cd-4486-9f9b-b42153b76d3a)" (RequestToken: a323e32a-614f-6a62-f4ee-01a952674903, H
andlerErrorCode: InvalidRequest)
```

This clearly shows that NodeGroup creation of EKS wont support Launch template with spot options.

### Expected Behavior

EKS Managed Node group creation to support Launch template with Spot options with CDK.

### Current Behavior

EKS Managed Nodegroup creation fails with following error :

```
7:02:50 PM | CREATE_FAILED | AWS::EKS::Nodegroup | blueprintconstruct...templatengECF74DC1
Resource handler returned message: "Instance market options are not supported with the launch template. (Service: Eks, St
atus Code: 400, Request ID: 2bc085ab-99cd-4486-9f9b-b42153b76d3a)" (RequestToken: a323e32a-614f-6a62-f4ee-01a952674903, H
andlerErrorCode: InvalidRequest)
```

### Reproduction Steps

Try to create a Launch template with following options and use the same while creating EKS Node Group.

const launchTemplateSpotOptions: ec2.LaunchTemplateSpotOptions = {
blockDuration: cdk.Duration.hours(1),
interruptionBehavior: ec2.SpotInstanceInterruption.STOP,
maxPrice: 10,
requestType: ec2.SpotRequestType.ONE_TIME,
validUntil: cdk.Expiration.after(cdk.Duration.days(90))
};

### Possible Solution

Adding support for EKS Managed Node group creation to support Launch template with Spot options with CDK.

Start by reproducing the provided TypeScript configuration and verify the AWS EKS error for launch-template spot options. The issue names no repository files or tests, so locate the EKS managed node group and EC2 launch template integration points before determining whether the requested combination can be supported. Done would mean successful node group creation with these options, or a documented limitation if AWS rejects the combination.
