`awsecs`: Golang - missing ecs optmized Bottlerocket images

### Describe the bug

Using the Golang CDK bindings, there is no `EcsOptimizedImage_Bottlerocket`. I only see the Amazon Linux ones and the Windows ones:

```
EcsOptimizedImage_AmazonLinux (options *EcsOptimizedImageOptions) EcsOptimizedImage
EcsOptimizedImage_AmazonLinux2 (hardwareType AmiHardwareType, options *EcsOptimizedImageOptions) EcsOptimizedImage
EcsOptimizedImage_Windows (windowsVersion WindowsOptimizedVersion, options *EcsOptimizedImageOptions) EcsOptimizedImage
```

https://github.com/aws/aws-cdk-go/blob/main/awscdk/awsecs/EcsOptimizedImage.go

However, I do see the correct binding in this repository in typescript:

https://github.com/aws/aws-cdk/blob/05a9fec6512bdddc387a7a5c98fa55f1ab3b5b64/packages/aws-cdk-lib/aws-ecs/lib/amis.ts#L288-L298

### Expected Behavior

I'd expect there to _also_ be the correct Bottlerocket ECS optimized ami in Golang as well:

```go
// The aws-ecs-1 variant of bottlerocket
EcsOptimizedImage_Bottlerocket (options *EcsOptimizedImageOptions) EcsOptimizedImage
```

### Current Behavior

Missing function in the `awsecs` Go library to the Bottlerocket optimized AMI

### Reproduction Steps

N/a

### Possible Solution

I thought the Go bindings were generated from this Typescript codebase. So I'm surprised to find that the `awsecs` Go package is missing the Bottlerocket AMIs. These should be added since the `aws-ecs-1` variant is supported by ECS.

### Other information

Compare awscdk/awsecs/EcsOptimizedImage.go with the Bottlerocket definitions in packages/aws-cdk-lib/aws-ecs/lib/amis.ts at lines 288-298. Confirm how the Go bindings expose the existing Amazon Linux and Windows images, then add the missing Bottlerocket binding consistently. Done means the awsecs Go library exposes EcsOptimizedImage_Bottlerocket for the aws-ecs-1 variant.
