Fix: `puppeteer-device-viewport-plugin` missing

[denstorti]

I had troubles today with version 2.3.1.

I got the following error when executing any gsts command, for example gsts --version:

$ gsts --version

internal/modules/cjs/loader.js:628
    throw err;
    ^

Error: Cannot find module './puppeteer-device-viewport-plugin'

  requireStack: [
    '/Users/denis.silva/.config/yarn/global/node_modules/gsts/index.js'
  ]
}

I notice the file puppeteer-device-viewport-plugin.js is not included in the package.json, and index.js imports it directly.

After I manually copied the file puppeteer-device-viewport-plugin.js to the gsts module (in my case, /Users/denis.silva/.config/yarn/global/node_modules/gsts) it worked fine.

Can you check it, please?

Cheers!
