Add double quote wrap in activate_python_virtual_environment (#7787)

Added double quote wrap in activate_python_virtual_environment to handle
spaces in path.
Would fail to find venv activate script when spaces exist.


Release Notes:

- Fixed venv_detection activation not finding directory if space is in
the path
