Fix code line in actions.py for spreadsheet info (#5887)
Fix code line in actions.py for spreadsheet info (#5887)

The code line should be updated to the specific portion of the code where the info is stored into a spreadsheet. In addition, after applying this fix it should be ensured that the links contained in the doc site (https://rasa.com/docs/rasa/user-guide/building-assistants) are correctly updated (previously incorrectly pointing to https://github.com/RasaHQ/rasa-demo/blob/master/demo/actions.py#L69 and delivering 404 error).
