Identify workflows that reference or are triggered by other repos

When migrating repos from ADO to GitHub, ADO pipelines that reference other ADO repos or are triggered by other repos will need references updated.

Add a utility to find and list all instances where pipelines reference other repos.

Notes:
* Search for ``` path:*.yml AND repo OR trigger ```
* Search API reference: https://learn.microsoft.com/en-us/rest/api/azure/devops/search/code-search-results/fetch-code-search-results?view=azure-devops-rest-7.1&tabs=HTTP

从 Azure DevOps 代码搜索 API 参考文档和建议的查询 `path:*.yml AND repo OR trigger` 开始。确定该实用程序应如何枚举 pipeline 引用和 repository-trigger 关系；当它列出迁移所需的每个匹配实例时即表示完成。
