Updating Cover Reports

Stop Cover Reports by running: docker compose down
In your shell, navigate to the $COVER_REPORTS_HOME directory where the existing installation is located and make a copy (backup) of the directory.
Rename the docker-compose.yml file in the $COVER_REPORTS_HOME directory - e.g. docker-compose-2023.08.13.yml
