Neural Global Entity Graph (GEG) Historical Backfile Updated With New Language Field

As the neural Global Entity Graph (GEG) expands beyond English, earlier this week we updated its BigQuery table to add a new "lang" field that contains the Google-assigned language code of the document. Today we have completed updating its complete historical JSON archive, adding this field in to all records, so those analyzing the JSON files can adjust their workflows now to incorporate this language information.
