non_dev_dependency groups option does not work with poetry

[alfonsomthd]

Environment

• deptry version: 0.25.1
• Python version: 3.12
• Operating system (e.g. Ubuntu 22.04, Windows 11): Fedora Linux 43

Describe the issue

Although I have the following dependency groups in pyproject.toml:
[tool.poetry.group.baremetal]
optional = false

[tool.poetry.group.baremetal.dependencies]
...

[tool.poetry.group.container]
optional = false

[tool.poetry.group.container.dependencies]
...

When I set them as non-dev dep. groups using non_dev_dependency_groups, it does not work:

pyproject.toml found!
pyproject.toml contains a [tool.poetry] section, so Poetry is used to specify the project's dependencies.
pyproject.toml does not have build-system.build-backend == 'setuptools.build_meta', so setuptools is not used to specify the project's dependencies.
pyproject.toml does not have build-system.build-backend == 'setuptools.build_meta', so setuptools is not used to specify the project's dependencies.
Warning: Trying to extract the dependencies from the dependency groups ['baremetal', 'container'] as regular dependencies, but the following groups were not found: ['baremetal', 'container']

Expected behavior

It should have set those groups a non-dev groups.
