Updates Node version

[svpernova09]

Lets change this block to the following to give more clarity and context:

# If you're not quite ready for the latest Node.js version,
# uncomment these lines to roll back to a previous version

# Remove current Node.js version:
#sudo apt-get -y purge nodejs
#sudo rm -rf /usr/lib/node_modules/npm/lib
#sudo rm -rf //etc/apt/sources.list.d/nodesource.list

# Install Node.js Version desired IE: 13
# More info:
#   https://github.com/nodesource/distributions/blob/master/README.md#debinstall
#curl -sL https://deb.nodesource.com/setup_13.x | sudo -E bash -
#sudo apt-get install -y nodejs

We're currently installing node 14 so the previous version would be 13. The link also gives users enough context to find older versions with the proper instructions for Ubuntu 20.04
