fix(artifacts): Widen exception handling for distribution notifications (EME-422)

Catch all exceptions (not just SentryClientError) when reporting
distribution errors/skips. Network errors like ConnectionError and
Timeout from requests aren't subclasses of SentryClientError, so they
would propagate uncaught and crash the pipeline. These are best-effort
notifications that should never block artifact processing.
