            # Motivation
            We would like to keep the testing environment, provided by snsdemo, up to date.

            # Changes
            * Updated `snsdemo` version in `dfx.json`.
            * Ensured that the `dfx` version in `dfx.json` matches `snsdemo`.

            # Tests
            CI should pass.
          # Since the this is a scheduled job, a failure won't be shown on any
          # PR status. To notify the team, we send a message to our Slack channel on failure.
