Merge branch 'minor_improvement' into 'main'

## Getting started

To deploy the service, run the following command in an Ubuntu or MacOS terminal.

```

    cd dummy-aef

    chmod +x start_dummy_api.sh

    ./start_dummy_api.sh <Username provided by organizers>

```

The above command will deploy a docker container with the name or username inserted

The API of this AEF, during the tutorial, has to be accessible via the [CAPIF Provider Gateway](https://labs.etsi.org/rep/ocf/provider-gateway)

First fill the fields starting with <> with the correct information and then copy them to the Provider Gateway folder.

To check the logs, run the following command.

```

 ./logs_dummy_api.sh <Username provided by organizers>

```

To stop the service, run the following command.

```

 ./stops_dummy_api.sh <Username provided by organizers>

```
