The config was moved out from `__main__.py` into `pyproject.toml`

You must add in your `pyproject.toml` the following stuff:
```toml
[manage_django_project]
module_name="your_project_example"

local_settings='your_project.settings.local'

test_settings='your_project.settings.tests'
```

The `config` argument was remove from `execute_django_from_command_line()`, so your `__main__.py`
must look like:

```python
from manage_django_project.manage import execute_django_from_command_line

def main():
    execute_django_from_command_line()

if __name__ == '__main__':
    main()
```
