fix: registry gc apdex/error ratio alerts
What
Stop paging on apdex and error ratio dips for the Container Registry Garbage Collector
Why
Garbage Collector can have transient issues and errors are retried, which can clear up the queue. A better alert is when we have queue backlog buildup which we are making it paging in !4786 (merged)
