Fix Python plugin venv loading

Updated the Python parser's dependencies to the latest version since
newer Python versions require a more recent version of the Jedi
parsing library to load the Python virtual environment (venv).

Also made a minor mix: failing to load a virtual environment
is a major misconfiguration issue, so the parser now exits
with and error.
