extra_dependency.update(poetry.get("extras", {}))

It looks like Poetry has updated their pyproject.toml formatting for dependency grouping: https://python-poetry.org/docs/managing-dependencies/

They no longer group all extra dependencies under "extras", but encourage the use of dependency groups.

Can liccheck be updated to support including the dependency groups used in Poetry in its reports?
