DEV: Remove unused rswag script

We no longer use this script for helping generate rswag formatted docs because we can use json schema now.

script/json_to_rswag.rb

-# This script is used for development to help document rswag api responses.  It
-# takes a json response string as an input and converts it to ruby in the format
-# that rswag wants so that you can copy+paste it into the appropriate spec rather
-# than typing it by hand.
-#
-# example:
-#
-# ruby script/json_to_rswag.rb '{"success":true,"active":true,"message":"Your account is activated and ready to use.","user_id":18}'
-#
-# will output:
-#
-# schema type: :object, properties: {
-#   success: { type: :boolean },
-#   active: { type: :boolean },
-#   message: { type: :string },
-#   user_id: { type: :integer },
-# }
