On my last trooper shift, I was somewhat confused by the CrawlAttemptFailureRatioTooHigh entry ( https://chrome-internal.googlesource.com/infra/infra_internal/+/master/doc/troopers/playbook.md#CrawlAttemptFailureRatioTooHigh ) because there's a lot of alert headers before it links to the Codesearch playbook, and some of the alerts in between have text in their entries, making it hard to tell that the  Codesearch alert entries are linked to the playbook link. 

It would be nice to merge the codesearch playbook into the main trooper playbook if possible. Otherwise, a simpler fix for now would be to rearrange the headers, so it's more clear that the codesearch alerts have their own playbook.
