rename id option to appId

[gr2m]

It will be easier to understand when using with an Octokit instance

const MyOctokit = Octokit.defaults({ authStrategy: createAppAuth })
const octokit = new MyOctokit({
  auth: {
    appId: 123,
    privateKey: PRIVATE_KEY
  }
})

is more clear than

const octokit = new MyOctokit({
  auth: {
    id: 123,
    privateKey: PRIVATE_KEY
  }
})
``
