Subject: [PATCH] Alerting: Fix insights panel for Grafana missed iterations
 (#110468)

* Alerting: Fix insights panel for Grafana missed iterations

Existing panel was copied from Mimir version, so it was using the
wrong metric as well as incorrect assumptions on the series labels

grafanacloud_instance_rule_group_iterations_missed_total ->
grafanacloud_grafana_instance_alerting_schedule_rule_evaluations_missed_total

parsing `rule_group` (ex. `/rules/12345/synthetic_monitoring;default`) ->
using `rule_title` directly

* Linting
