Add warning on the daemon install page so that new users know to only install wings with 1.0+
To be clear, I don't know exactly how this doc software works, so let me know if I did this wrong.
Due to the new command change 'npm install --only=production --no-audit --unsafe-perm' instead of 'npm install --only=production', and due to the ``--no-audit' flag, the warning isn't needed.
Updated Supported Systems table for all the installs so they all match.
Removed 14.04/16.06
Removed REHL/Alpine/Fedora
Removed old versions of Debian/CentOS
Added newer versions of Debian/CentOS
Added Ubuntu 20.04
Removed duplicate supported game, Terraria
