feat(CodeBuild): Ensure source repository URLs do not contain sensitive credentials

[MarioRgzLpz]

Context

To improve security and adhere to best practices for code repository management, we are adding a new check within the CodeBuild framework. This check ensures that source repository URLs (right now only Bitbucket) do not contain sensitive credentials like authentication tokens or username and password.

Description

I added codebuild_bitbucket_urls_no_sensitive_credentialscheck with respective unit tests. In order to that I modified codebuild_service.py to add two new attributes source secondary_sources to the Project model, a new model Source and added respective test to codebuild_service_test.py.

Please name the check codebuild_project_source_repo_url_no_sensitive_credentials and create a BaseModel called Source to fill it with the information needed.
