Record unhanlded JMS exceptions as observation errors

Prior to this commit, when using the `DefaultMessageListenerContainer`
as a backing listener container for JMS messages, the instrumentation
would not record JMS exceptions as observation errors when they were not
handled by configured `ErrorHandler`.

This commit ensures that this is the case.

Fixes gh-32458
