{- 👉 TODO: replace the calls to `hardcoded` with calls to `required`
in order to decode these fields:
--- "description" -------> description : String
--- "title" -------------> title : String
--- "tagList" -----------> tags : List String
--- "favorited" ---------> favorited : Bool
--- "favoritesCount" ----> favoritesCount : Int
Once this is done, the articles in the feed should look normal again.
💡 HINT: Order matters! These must be decoded in the same order
as the order of the fields in `type alias Metadata` above. ☝️
