There are multiple `versions` defined in this repository

[GRiMe2D]

What

The repository version should be specified in one file

Why

To reduce version bumping issues

Objective

version.js defined the executables version. It is used to print for -v command. package.json defines its own version for NPM related tasks.

They should be unified.

How

Version needs to be regularly bumped and maintained. We can automate this by allowing CI/CD do this job.

Cannot be done currently. If we automate this, we need to disable protected branch
