Kyle Brennan 598b5372e8 [obs] Refactor alerts for image builds
For the last 30 days:

GitpodImagebuildDoneSuccess would have triggered once, on January 26 if set to 2h, instead of 4h.  A customer was potentially struggling with the outer loop. We hit a 60% error rate in Pyrra briefly: https://pyrra.gitpod.io/objectives?expr={__name__=%22workspace-imagebuild-buildsdone-success-ratio%22,%20namespace=%22monitoring-central%22,%20team=%22workspace%22}&grouping={}&from=1673297716785&to=1675716916785

GitpodImagebuildStartSuccess would have fired once, on Jan 8, when GCP was having scaling issues, and would have been correct to do so. https://gitpod.slack.com/archives/C01TNS8EVQT/p1673173223060219

Removed the warnings because they're unnecessary. Why? Pyrra sends them now for SLOs to #team-workspace-alerts.
