title: how to rollback to previous build in azure devops using yaml
body: <p>I have a multi-stage pipeline YAML deploying to different environments (PreDev-Dev-QA-Stage-Prod) and i'm trying to implement rollback strategy to rollback to previous version or previous build artifact and was looking at this page <a href="https://docs.microsoft.com/en-us/azure/devops/pipelines/process/deployment-jobs?view=azure-devops" rel="noreferrer">https://docs.microsoft.com/en-us/azure/devops/pipelines/process/deployment-jobs?view=azure-devops</a> but couldn't figure out and also didn't find any examples. Any help is appreciated</p>
