fix: log edited comment events at debug level instead of error

Edited or deleted issue comments on GitHub trigger a webhook that
reaches processEvent(), which returned an error for any non-"created"
action. That error propagated up to sinker and was logged as Errorf,
producing scary log entries for a normal, harmless event.

Replace the error return with a debug log and nil,nil return so these
events are silently skipped, matching the existing skip pattern used
elsewhere in the file.
