Hi! I've created a PR (#62094) to add Turkish (tr) translation guidelines following the same structure as the Simplified Chinese guidelines in #62059.
The Turkish guidelines are ready for review at: https://github.com/umutKaracelebi/airflow/blob/translation-guidelines-turkish/.github/skills/airflow-translations/locales/tr.md
Looking forward to feedback!
