The tests fail because yargs detects the OS' locale

I can do a PR for the issue if you want.

Expected Behavior

The tests should pass when cloning & installing the project.

Current Behavior

They do not. See:

  CLI tests
    ✕ Running without parameters should display help (94ms)
    ✕ Running without parameters should display a requirement for the p option (85ms)
    ✕ Linting a file that has wrong host should display an error message and use exit code 1 (76ms)
    ✓ Linting a file that has wrong host should return exit code 1 (74ms)

  ● CLI tests › Running without parameters should display help

    expect(received).not.toBe(expected) // Object.is equality

    Expected: not -1

      17 |       expect(output.indexOf('Usage:')).not.toBe(-1)
      18 |       expect(output.indexOf('Options:')).not.toBe(-1)
    > 19 |       expect(output.indexOf('Examples:')).not.toBe(-1)
         |                                               ^
      20 |       done()
      21 |     })
      22 |   })

      at Socket.toBe (__tests__/cli.test.js:19:47)

That’s because my locale is set to the french one, and yargs translates the CLI output (at least some of it) (See https://github.com/yargs/yargs/blob/master/docs/api.md#detectlocaleboolean Your tests rely on the fact that the user has an english locale.

See the output of the npx lockfile-lint -h command:

Usage: lockfile-lint --path <path-to-lockfile> --allowed-hosts yarn npm

Options:
  --version              Affiche le numéro de version                  [booléen]
  --help, -h             Affiche de l'aide                             [booléen]
  -p, --path             path to the lockfile     [chaine de caractère] [requis]
  -t, --type             lockfile type, options are "npm" or "yarn"
                                                           [chaine de caractère]
  -s, --validate-https   validates the use of HTTPS as protocol schema for all
                         resources                                     [booléen]
  -e, --empty-hostname   allows empty hostnames, or set to false if you wish for
                         a stricter policy              [booléen] [défaut: true]
  -a, --allowed-hosts    validates a whitelist of allowed hosts to be used for
                         resources in the lockfile                     [tableau]
  -o, --allowed-schemes  validates a whitelist of allowed schemes to be used for
                         resources in the lockfile                     [tableau]

Exemples:
  lockfile-lint --path yarn.lock --validate-https
  lockfile-lint --path yarn.lock --validate-https --allowed-hosts npm yarn
  verdaccio
  lockfile-lint --path yarn.lock --allowed-schemes "https:" "git+ssh:"
  --allowed-hosts npm yarn verdaccio

Possible Solution

Adding

.detectLocale(false)

to the lockfile-lint/src.main.js file works.

Steps to Reproduce (for bugs)

Well, I don’t know how to set my locale to another, but I guess https://www.tecmint.com/set-system-locales-in-linux/ should help

1. Clone the project
2. Install the dependencies
3. Launch the tests

Context

I was trying to improve the output of the expected protocol; I’ve tried to analyze one of my project’s lockfile and I was surprised at the output (I expected HTTPS, not https:, do you want to a PR for that?)
