ci: Add GitHub Workflow

[seanpoulter]

Description

Add a GitHub Workflow

• Add .nvmrc
• Extract the "lint" npm script
• Replace .codeclimate.yml and .travis.yml with .github/workflows/ci.yml

Checklist

• Unit/Integration test added (if applicable)
• Documentation added/updated (wiki or md)
• Code style is consistent with the rest of the project

Background

• I expect this to help keep the updates in Update service to ESM and WDIO v8 #126 smaller. The tests will fail until we fix the problems with ChromeDriver.
• I expect that we are not using Travis CI or Code Climate anymore

LGTM 👍

The Workflow fails in test:app. It downloads Chromedriver 112 which we do not expect to work with Chrome 122. That should be fixed in #126 as we upgrade from v7 to v8.
