Wrong video embedded on Korean page.

Issue in ./help/analysis-workspace/dimensions/introduction-to-traffic-variables-props.md

Korean version page has wrong video embedded. It's not about the traffic variable, but about basic visitor metrics.
It seems to be the same one as the page prior to this page. (this one -> [Understanding Basic Visitor Metrics](https://experienceleague.adobe.com/docs/analytics-learn/tutorials/analysis-workspace/metrics/understanding-basic-visitor-metrics.html?lang=en))

Open ./help/analysis-workspace/dimensions/introduction-to-traffic-variables-props.md and inspect the video embed on the Korean version page. Compare it with the linked Understanding Basic Visitor Metrics page and confirm the embedded video is about traffic variables rather than basic visitor metrics.
