Automate selection of latest Processing releases

Added logic to fetchReleases.js to automatically select the latest stable release for each major Processing version and update selected.json accordingly. Also updated processing-1310-4.4.10.json to mark the release as stable and adjusted selected.json to reflect the new selection logic.
