Update dependency yeoman-generator to ^2.0.0

[renovate]

This Pull Request updates dependency yeoman-generator from ^1.1.1 to ^2.0.0

Release Notes

v2.0.0

This release fix a few bugs and focus on modernizing our codebase to ES6 style.

Breaking changes

• Generator.extend() is replaced in favor of class extends Generator {}
• Generator#github.username() now returns a promise instead of taking a callback
• Install functions now returns promises (installDependencies, runInstall, bowerInstall, npmInstall and yarnInstall)

New features

• installDependencies now accept command line arguments as options for each sub-command (#​1014)

    this.installDependencies({
      npm: {saveDev: true},
      bower: {depth: 0}
    });

Fix

• Fix diffing dying on empty files (#​1028)

---

v2.0.1

• Bump dependencies (including security patch on debug)

---

v2.0.2

• Fix error when the prompt choices options is provided as a function instead of an array. (Drawback: this will turn off Yeoman reuse of the previously provided answer)

---

v2.0.3

• Update dependencies with security vulnerabilities.
