Usage of deprecated save_json

Detected integration that uses save_json from homeassistant.util.json module. This is deprecated and will stop working in Home Assistant 2022.4, it should be updated to use homeassistant.helpers.json module instead. Please report issue to the custom integration author for microsoft_todo using this method at custom_components/microsoft_todo/calendar.py, line 87: save_json(hass.config.path(MS_TODO_AUTH_FILE), token)
