[AWS::CodeBuild::Project] - [expose scope prop to the construct.] - AWS code build webhook scope configuration for GitLab

### Name of the resource

AWS::CodeBuild::Project

### Resource name

_No response_

### Description

https://github.com/aws/aws-cdk/issues/34146

There's a discrepancy between the AWS CodeBuild API and the CloudFormation specification for the ScopeConfiguration property of AWS::CodeBuild::Project.

The CodeBuild API documentation (https://docs.aws.amazon.com/codebuild/latest/APIReference/API_ScopeConfiguration.html) shows that ScopeConfiguration should have both a name property and a scope property, with the latter being required and accepting values like 'GITHUB_ORGANIZATION', 'GITHUB_GLOBAL', or 'GITLAB_GROUP'.

However, the CloudFormation specification for AWS::CodeBuild::Project [ScopeConfiguration](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-codebuild-project-scopeconfiguration.html) only includes the name property.

This prevents users from properly configuring GitLab webhooks through CloudFormation or CDK, as it defaults to 'GITHUB_ORGANIZATION' without the ability to set it to 'GITLAB_GROUP'.

### Other Details

_No response_

The issue identifies AWS::CodeBuild::Project and its ScopeConfiguration property; start with the linked aws/aws-cdk#34146 issue and the AWS API and CloudFormation specification pages. Done means the scope property can be configured for values such as GITLAB_GROUP rather than defaulting to GITHUB_ORGANIZATION.
