fix(python): Read venv prompt from pyvenv.cfg (#1747)

*  Add  --prompt rendering to python virtualenv

* Use pyvenv.cfg to find prompt

* Remove usage of VIRTUAL_ENV_PROMPT variable

Seeing how both venv and virtualenv set a pyvenv.cfg, this isn't needed.
Additionally pyvenv.cfg is set in earlier versions than VIRTUAL_ENV_PROMPT,
which at this moment is in the unrelased python 3.10

* Smarter result unwrapping thanks to clippy
