Update quickstart.md

[sspkash]

Add the django package to the pip install command.

Description

In the Quickstart webpage, the first code snippet under the Project setup section contains a small discrepancy.

As per the comment/description # Install Django and Django REST framework into the virtual environment, the following command pip install djangorestframework does not include the django package.

This pull request fixes the discrepancy by changing the command pip install djangorestframework to pip install django djangorestframework.

DRF depends on Django, so pip will install it if it's not present in your environemnt. I'd say that in 99% of the case, if you install DRF, you already have Django.

Fair enough, thanks for the info :)
