[Dependencies] Bump Event Hubs version (#8545)

The focus of these changes is to bump the reference for `Azure.Messaging.EventHubs` to the latest version.   There have been a number of fixes and enhancements in the 9 months since the previously version was released.  Of particular note, there were two important fixes in the AMQP transport library which could cause corruption in the connection state until the process was restarted.

Details can be found here: https://github.com/Azure/azure-sdk-for-net/blob/Azure.Messaging.EventHubs_5.9.2/sdk/eventhub/Azure.Messaging.EventHubs/CHANGELOG.md
