GitHub Pages Response Out of Date

[rreichel3]

The GitHub Pages API response appears to be a bit out of date. There are new additional fields for GitHub Pages that aren't included in the struct. These include information about the visibility of the page, certificate issuance info and whether or not HTTPS is enforced.

The additional properties required are visible in the docs here but specifically are as follows:

  "public": true,
  "https_certificate": {
    "state": "approved",
    "description": "Certificate is approved",
    "domains": [
      "developer.github.com"
    ],
    "expires_at": "2021-05-22"
  },
  "https_enforced": true

I'm planning on working on this over the next few days and hope to have a PR soon.
