Upgrade Node from v16

[AetherUnbound]

I'm seeing this warning locally when building the image:

 => => #                           SCRIPT DEPRECATION WARNING

 => => # Continuing in 60 seconds (press Ctrl-C to abort) ...                                                                                                                                

I believe it's coming from our Node installation script: wget -O - https://deb.nodesource.com/setup_16.x. It might be addressed by the upstream batches but I wanted to make note of it before I forgot!

This should be fixed by #362
