Node version not specified

[ahaim5357]

The repository does not contain the required node version needed to run the platform. Additionally the instructions on the Google collab seem to differ on what to do with setting up the platform compared to that on the readme.

The node version should go in a .node-version file with some instructions or links provided for setting up with nvm (Unix)/nvs (windows).

On WSL2 with Ubuntu 20.04 the default apt install nodejs errors with

This seems related to nodejs/node#37972 which suggests that version 14.16.0 solves the issue while the default on WSL2 was version 10.19.0. Not sure if there are other issues that require a newer version than 14.16.0 though.
