Pretty Print JSON responses from `curl`

When you use curl to manually make API calls, sometimes the response is not formatted:

> curl 'https://til.hashrocket.com/api/developer_posts.json?username=gabrielreis'`

{"data":{"posts":[{"title":"Display line break content in React with just CSS","slug":"mmzlajavna"},{"title":"Mutations with the graphql-client Ruby gem","slug":"xej7xtsnit"},{"title":"The rest of keyword arguments 🍕","slug":"o2wiclcyjf"}]}}%

You can pipe json_pp at the end so you have a prettier json response:

> curl 'https://til.hashrocket.com/api/developer_posts.json?username=gabrielreis' | json_pp

{
   "data" : {
      "posts" : [
         {
            "slug" : "mmzlajavna",
            "title" : "Display line break content in React with just CSS"
         },
         {
            "title" : "Mutations with the graphql-client Ruby gem",
            "slug" : "xej7xtsnit"
         },
         {
            "title" : "The rest of keyword arguments 🍕",
            "slug" : "o2wiclcyjf"
         }
      ]
   }
}
