Demo Installer for MacOS computers requirer wrong Node version

Quick summary of the problem:

• Open Search Dashboard ships with NodeJS binary for AMD processors
• To workaround this problem we are using local Node version provided by the user hardcoded in
• The required Node version has been changing between OSD releases

Proposed solution:

• Create a matrix with OSD and required Node versions that can be expanded if the future versions will require a specific node version.
