Subject: [PATCH] poetry: invoke poetry.console.main instead of using
 env_script_all_files

Poetry interfaces with virtualenvs, and when PYTHONPATH is set it does not
operate correctly.

Our `bin/poetry` is now functionally the same as the official poetry
distribution's `bin/poetry`.

Relates to #50673, and https://github.com/python-poetry/poetry/issues/1929.
