docs: language changes and clarify instructions (#709)

- Update the language to be more aligned with a tutorial, i.e., a learning experience we're going on together
- Clarified instructions in the "Update Django application" section to replace the contents of the time_app/views.py and django_hello_world/urls.py files. If the user inserts the contents without replacing the previous text, this leads to an Internal Service Error when the user sends a request to the /time/ endpoint.
