Add log message for receiving notifications

Follow up from https://code.chs.usgs.gov/ghsc/hazdev/cdk/anss-pdl/-/issues/328

Notifications received are no longer logged on the FINE level after the product tracker was removed. And now the notification widgets on the anss-pdl dashboard do not work.

AC:

• add logging message to https://code.usgs.gov/ghsc/hazdev/pdl/-/blob/main/src/main/java/gov/usgs/earthquake/distribution/DefaultNotificationReceiver.java?ref_type=heads#L170-L187
• This log insights query line parse @message "source=*, type=*, code=*, updateTime=*" as source, type, code, updateTime should still work
