Auto-link generation is still happening in some example code parts

On page https://syslog-ng.github.io/admin-guide/120_Parser/023_db_parser/002_Triggering_actions/002_Actions_and_message_correlation in the last xml example we still have an auto-linked keyword

In this https://syslog-ng.github.io/admin-guide/130_Correlating_log_messages/000_Correlating_messages_with_grouping-by it is correct.

Investigate why.
