What this PR does
This PR increases the pending period for MimirBucketIndexNotUpdated by 5 minutes to reduce the false positives we've observed over the past few weeks. As I understand it, the pending period determines how long the condition must exceed the threshold before the alert fires—so with this change, the alert will only trigger if the threshold is exceeded for more than 5 minutes.
