refactor: extract possible location

[JuanVqz]

• [x] add possibleLocations.js helper file

I wanted to create a test but I don't know how to stub process.env.HOME, process.env.APPDATA in mocha, in fact, I haven't experienced doing testing in javascript,

I read a lot and I think jest it's a good option to go, what do you think?

This test will fail when the /home/itox/ changes in another machine. ex. into the CI. do you know how to solve it?

const assert = require('assert');

const { possibleLocations } = require('../../bin/helpers/possibleLocations');

describe('possibleLocations', () => {
  it('returns two locations by default', () => {
    assert.deepStrictEqual(possibleLocations(), [
      '/home/itox/.config/alacritty/alacritty.yml',
      '/home/itox/.alacritty.yml',
    ]);
  });
});
