Update code examples in building-a-login-with-github-button-with-a-github-app.md

[arthurgubaidullin]

Remove unnecessary body from http get request

Why:

Sending body in a get request is redundant.

What's being changed (if available, include any code snippets, screenshots, or gifs):

I corrected the code examples in sections:

• Add code to generate a user access token
• Full code example

What's fixed:

def user_info(token)
  uri = URI("https://api.github.com/user")

  result = Net::HTTP.start(uri.host, uri.port, use_ssl: true) do |http|
-    body = {"access_token" => token}.to_json

    auth = "Bearer #{token}"
    headers = {"Accept" => "application/json", "Content-Type" => "application/json", "Authorization" => auth}

-   http.send_request("GET", uri.path, body, headers)
+   http.send_request("GET", uri.path, nil, headers)
  end

  parse_response(result)
end
