Alerting: Update grafana/alerting (#88363)
* Alerting: Update grafana/alerting

* make tests pass by implementing yaml unmarshallers and deleting fields with omitempty in their yaml tags

* go mod tidy

* fix tests by implementing not calling GettableApiAlertingConfig.UnmarshalYAML from GettableApiAlertingConfig.UnmarshalJSON

* cleanup, reduce diff

* fix more tests

* update grafana/alerting to latest commit, delete global section from configs in tests

* bring back YAML unmarshaller for GettableApiAlertingConfig

* update alerting package dependency to point to main

* skip test for sns notifier
