For Python3, venv is used (rather than virtualenv). Updating the documentation to reflect the updated commands for the virtual environment setup.
Also updates node version to a more recent one (old one is no longer used) when setting up Node.js environment.
Finally, adding && \ in between commands for installing GRR packages. This way, we'll stop installation in the first failure (avoids missing issues).
