vdk-control-cli: Add python_version to sample config.ini (#2555)

This change adds the `python_version` property to the config.ini file of
the sample data job that is returned when a user executes `vdk create -n
<job-name> -t <team-name>`. The property is commented out, as it is used
only if a user wants to set a python version different from the default
one.

Testing Done: Executed `vdk create -n my-test-job -t my-team` locally,
and verified that the python_version property is present in the
generated data job's config.ini file.
