Python Poetry package manager support

[joachimBurket]

Is your feature request related to a problem? Please describe.
The extension needs a requirements.txt to work, so Python projects using Poetry are not supported by default.

Describe the solution you'd like to see
Support Poetry projects (with the dependencies listed in the pyproject.toml file.

Describe alternatives you've considered
Manually export the dependencies from the virtualenv in a requirements.txt file with

pip freeze > requirements.txt

Additional context

I ran in the same issue. When I create an empty (!) requirements.txt file, the extension discovers my virtual environment and performs the scan correctly.
