Rendering a nested pyproject.toml file to stdout is broken

[jameslamb]

Discovered this today while working on rapidsai/cudf#15245.

On the latest version of dependency-file-generator (v1.13.4), rendering a nested pyproject.toml to stdout fails.

Reproducible Example

git clone [email protected]:rapidsai/cudf.git
cd cudf
git checkout b810113d

rapids-dependency-file-generator \
  --output pyproject \
  --file-key py_run_cudf \
  --matrix "cuda=12.2"

Fails like this:

Traceback (most recent call last):
  File "/Users/jlamb/miniforge3/envs/rapids-dev/lib/python3.10/site-packages/rapids_dependency_file_generator/_rapids_dependency_file_generator.py", line 183, in make_dependency_file
    table = table[section]
  File "/Users/jlamb/miniforge3/envs/rapids-dev/lib/python3.10/site-packages/tomlkit/container.py", line 624, in __getitem__
    item = self.item(key)
  File "/Users/jlamb/miniforge3/envs/rapids-dev/lib/python3.10/site-packages/tomlkit/container.py", line 466, in item
    raise NonExistentKey(key)
tomlkit.exceptions.NonExistentKey: 'Key "project" does not exist.'

During handling of the above exception, another exception occurred:

  File "/Users/jlamb/miniforge3/envs/rapids-dev/bin/rapids-dependency-file-generator", line 10, in <module>
    sys.exit(main())

    contents = make_dependency_file(

    if not table.is_super_table():
AttributeError: 'TOMLDocument' object has no attribute 'is_super_table'

Notes

I believe the specific issue is right here:

dependency-file-generator/src/rapids_dependency_file_generator/_rapids_dependency_file_generator.py

Line 418 in ec3d043

output_dir = "." if to_stdout else get_output_dir(file_type, parsed_config.path, file_config)

I have a fix for this, will put up a PR shortly. Just wanted to get the bug into writing.
