Replace 👨‍💻 to something more diverse

[cy]

I know I approved https://github.com/prodigyeducation/branch-cleaner/pull/45 and I understand the reason for replacing the Ed icon, but now when I see the 👨‍💻 icon I feel like it doesn't really represent the person the branch belonged to.

How about we use the 'status.emoji' field on github to allow users to select their own emoji? This thing:

We can retrieve it on a github user type like

query { 
  viewer { 
    login
    status {
      emoji	
    }
  }
}

returns

{
  "data": {
    "viewer": {
      "login": "cy",
      "status": {
        "emoji": ":woman_technologist:"
      }
    }
  }
}

and by default we can display the gender neutral 💻
