Traducir contenido de archivo Poedit

Esta consulta GraphQL traduce las cadenas vacías de un archivo Poedit (ejecutando una única llamada a la API de Google Translate) que es accesible desde alguna URL, y añade esas traducciones en la entrada correspondiente de un nuevo archivo de traducción Poedit, para algún idioma.
Después sube el archivo de traducción a Filestack, bajo la aplicación correspondiente a la clave API dada.
Tras ejecutar la consulta, la URL con el archivo subido se imprimirá bajo la entrada uploadedFileURL.

# === Description ===
#
# This Persisted GraphQL query translates the empty strings from a
# Poedit file (by executing a single call to the Google Translate API),
# and adds those translations in the corresponding entry of a new
# translation Poedit file.
#
# It then uploads the translation file to Filestack (https://www.filestack.com)
