Fix yamls and bash script

## Description

For the sake of SNS4SNS 2026 OCF tutorial, this project is provided to work as an API Exposing Function (AEF).

For the SNS4SNS 2026 OCF tutorial, this project is provided to work as an API Exposing Function (AEF).

The service is a simple Flask server, hosting a GET request.

```

GET /hello

```

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

The neccesary files to configure the Provider Gateway with the AEF API are:

- northbound.yaml

- southbound.yaml

First fill the "..." of the above fiels with the correct information and then use then to Provider Gateway.

### Prerequisites

- Docker (tested in version 29.1.3)

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

```

 ./start_dummy_api.sh <Participant name or username>

 ./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)

The neccesary files to configure the Provider Gateway with the AEF API are:

- northbound.yaml

- southbound.yaml

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

    return jsonify(f"Hello, {app_name}!")
