Integrate with GitHub Node.js package

[thyarles]

To get more useful information and drive best the cy-runner decisions, we need to take advantage of Octokit from GitHub.

Something like that.

import { Octokit } from '@octokit/rest'

export class GitHubInfo {  
  public ref: GithubRef
  public repo: GithubRepo
  public owner: GithubUser
  public sender: GithubUser
  public installation: string

  constructor({ ref, repo, owner, sender, installation }: any) {
    this.ref = ref
    this.repo = repo
    this.owner = owner
    this.sender = sender
    this.installation = installation
  }
}
