Sync named function parameters to Crowdin

[bethanyaconnor]

This PR adds the named parameters to the function_definitions object for each level. I'll create a separate PR to actually use the translations.

Example:

  "https://studio.code.org/p/artist": {
   ...
    "function_definitions": {
      "draw a star": {
        "name": "draw a star",
        "description": "draw a star with given points and sides of given length",
        "parameters": {
          "points": "points",
          "length": "length"
        }
      },
      "draw a circle": {
        "name": "draw a circle",
        "description": "draw a circle of given radius",
        "parameters": {
          "radius": "radius"
        }
      }
      ...
  }
}

I'd love to see this get DRYed out a bit. Something like

      functions.each do |function|
        name = function.at_xpath('./title[@name="NAME"]')
        description = function.at_xpath('./mutation/description')
        parameters = function.xpath('./mutation/arg').map do |parameter|
          [parameter["name"], parameter["name"]]
        end.to_h

        definition = Hash.new
        definition["name"] = name.content if name
        definition["description"] = description.content if description
        definition["parameters"] = parameters unless parameters.empty?

        i18n_strings['function_definitions'][name.content] = definition
      end

Good call. I'll update it.
