Update lint:dependencies #450
Description
Summary
In #236 , the lint:dependencies nox task was added. As demonstrated in #449 , reading of the pyproject.toml has changed with poetry 2.x. We should use the newly added structures from #449 to update lint:dependencies and also check how dependencies not from pypi would now be defined. (Is it still inline or with [tool.hatch.sources] for the project.dependencies?).
Additionally, this check was not added to the CI as was written in #236. It should be double-checked that we want it added and, if so, added.
