fix: Return message

Pull Request Template

Description

While working on the GCBM Demo for the route POST /gcbm/title I discovered that the return message did not include the title of the simulation one is working on. So I included the f function for printing out the return message correctly.
Another thing, when one is testing the GCBM locally, with the instructions on the README.md file, there was a confusion on the terminals that you are supposed to be working with. So I edited this the right terminal for the docker container to be running on, and the terminal to test using curl command.
