          Automated Node.js version update:

          - Node 20: ${{ steps.node-versions.outputs.current_node20 }} → ${{ steps.node-versions.outputs.latest_node20 }}
          - Node 24: ${{ steps.node-versions.outputs.current_node24 }} → ${{ steps.node-versions.outputs.latest_node24 }}

          This update ensures we're using the latest stable Node.js versions for security and performance improvements.

          **Note**: When updating Node versions, remember to also create a new release of alpine_nodejs at the updated version following the instructions at: https://github.com/actions/alpine_nodejs
