Remove Issue Correlation page (#37718)

* Remove Issue Correlation page and nav entries

Feature no longer exists; removed the page and all menu entries across EN, FR, ES, JA, and KO nav files.

* Delete Spanish translation and add redirect alias

- Remove content/es/error_tracking/issue_correlation.md (translated page still present)
- Add aliases redirect on _index.md so old URLs don't 404
