Alerting: Fix NoData & Error alerts not resolving when rule is reset (#80184)
* Alerting: Fix NoData & Error alerts not resolving when rule is reset
On rule reset, when creating the PostableAlerts StateToPostableAlert did not
attach the correct NoData/Error alertname and rulename labels to expire/resolve
the active alerts when the previous cached state was NoData/Error.
