json file for housing contributors info

[mathcodes]

URGENT: create a db.json file that holds contributors' info and an id (id, avatar_url, github_url) where each object in the JSON data has a key = contributor's GitHub handle like so:

{
  "mathcodes": {
    "id": "0",
    "avatar_url": "https://avatars.githubusercontent.com/u/17928947?v=4",
    "github_url": "https://github.com/mathcodes/",
  },
  "<NEXT_CONTRIBUTOR HANDLE": {
    "id": "0",
    "avatar_url": "<AVATAR_URL>",
    "github_url": "<GITHUB_URL>",
  },
...
}
