Description

Is your feature request related to a problem? Please describe.

Hello, we use emit_unmatched so user knows which ip/host sent the failed syslog message. Can the warning message (failed to parse/ invalid syslog/ etc) be added to the emit_unmateched message as well?

Describe the solution you'd like

Add the logged warning message to emit_unmatched

Describe alternatives you've considered

Contributor guide

Research direction
Look at the syslog input plugin, likely in `lib/fluent/plugin/in syslog.rb`. The `emit unmatched` feature currently outputs the raw unmatched line, but the request is to also include the warning message (e.g., parsing failure). Check where warnings are logged (e.g., `log.warn` calls) and modify the emit unmatched method to append that message to the event. Review the existing comments on the issue for any further clarification.
