docs: getting_started: change default python setup to use virtual env

Browse source 
Change default python setup suggested in getting started guide to use
virtual environments. This aligns with the documentation itself, which
suggests that users use virtual environments with Zephyr. The Windows
python setup is also updated with the correct command to create a
virtual environment, as "python3" is not a defined executable in a
windows commandline after installing python with chocolatey

additional Python dependencies.
Python is used by the ``west`` meta-tool as well as by many scripts invoked by
the build system. It is easy to run into package incompatibilities when
installing dependencies at a system or user level. This situation can happen,
for example, if working on multiple Zephyr versions at the same time. For this
reason it is suggested to use `Python virtual environments`_.
