Pull Request Description

Summary

The custom exports page explains how to add a new export filter, but not how to adapt one of the existing ones. I added a short section in en/collaborative-work/export/customexports.md based on the steps Siedlerchr described on the forum (https://discourse.jabref.org/t/export-custom-field/4501), using the CSV export as an example. I also mentioned two points that caused problems in that thread (selecting the exporter as file type and writing field names in lowercase), and replaced the outdated reference to the download page with a link to the layout files on GitHub.

Steps to test

Open JabRef and follow the steps of the new section "Modifying an existing export filter" on the custom exports page. After exporting, the CSV file should contain the new column with the field value.

Custom export format in the preferences:

Exported CSV with the new column:

High-Level Assessment

Extending the existing custom-exports page is appropriate: the CSV walkthrough builds on its layout-file guidance without duplicating a separate guide.
