Unable to use AWS code build webhook scope configuration for GitLab

### Describe the feature

CreateWebhook [1] in CodeBuild API provides a way to configure scope and domain in scopeConfiguration object. Valid Values of scope are : GITHUB_ORGANIZATION | GITHUB_GLOBAL | GITLAB_GROUP as per [2]. However when I try to create a CodeBuild project using CDK with scope value set, I see an error. If no scope value is set, it defaults to GITHUB_ORGANIZATION for my GITLAB configuration and the update fails.

[2] https://docs.aws.amazon.com/codebuild/latest/APIReference/API_ScopeConfiguration.html#CodeBuild-Type-ScopeConfiguration-scope

### Use Case

Create a GitLab Runner Project via CDK

### Proposed Solution

Update the scope configuration property

### Other Information

_No response_

### Acknowledgements

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

### CDK version used

2.189.0

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

Linux, windows

Start at the aws_cdk_lib.aws_codebuild.CfnProject.ScopeConfigurationProperty entry point and compare its scope options with the CreateWebhook and ScopeConfiguration AWS API documentation linked in the issue. The change is done when a GitLab project can use the GITLAB_GROUP scope configuration without defaulting to GITHUB_ORGANIZATION or failing during update.
