Fix SQL Server metrics from gauge to monotonic sum

CHANGELOG.md

@@ -39,6 +39,7 @@
 - `resourcedetectionprocessor`: Wire docker detector (#9372)
 - `kafkametricsreceiver`: The kafkametricsreceiver was changed to connect to kafka during scrape, rather than startup. If kafka is unavailable the receiver will attempt to connect during subsequent scrapes until succcessful (#8817).
 - `datadogexporter`: Update Kubernetes example manifest to new executable name. (#9425).
+- `sqlserverreceiver`: Update `sqlserver.transaction_log.growth.count` and `sqlserver.transaction_log.shrink.count` to be monotonic sums. (#9522)
