(@aws-cdk/aws-codedeploy): Add support for Triggers property in ServerDeploymentGroup cdk construct

### Describe the feature

Currently [ServerDeploymentGroup](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-codedeploy.ServerDeploymentGroup.html) construct does not provide prop for adding triggers which are available in [CfnDeploymentGroup](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-codedeploy.CfnDeploymentGroup.html).

### Use Case

Trigger prop would allow configuring triggers for the deployment group in the construct.

### Proposed Solution

_No response_

### Other Information

_No response_

### Acknowledgements

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

### CDK version used

2.192.0

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

N/A

Start by locating the ServerDeploymentGroup construct and the CfnDeploymentGroup construct in the @aws-cdk/aws-codedeploy package, then compare how the underlying deployment-group properties are exposed. Check the package's existing construct tests before adding coverage; done means users can configure deployment triggers through ServerDeploymentGroup and the synthesized deployment group includes them.
