Match the action versions the desktop workflows already use

The runner reported setup-java v4 deprecated and every v4 action forced onto
Node 24. release.yml is already on checkout@v6, upload-artifact@v6,
download-artifact@v7 and action-gh-release@v3, so there is no reason for this
workflow to sit a major version behind the one beside it.
