Solve the "Keep Shopping" link so it directs the user back to the page it came from.

The bag is fixed by following two steps:

1. Amend the product_display.html View link by adding a query paramater '?next={{ request.path }}' This adds a query parameter named "next" with the value set to the current page's URL (request.path)
2. In the product_detail.html, use the following structure to retrieve the previous page from the 'next' query:

> {% if request.GET.next %}
>     <a href="{{ request.GET.next }}" class="btn btn-outline-black rounded-0 mt-5">
>         <span class="icon">
>             <i class="fas fa-chevron-left"></i>
>         </span>
>         <span class="text-uppercase">Keep Shopping</span>
>     </a>
> {% else %}
>     <a href="{% url 'home' %}" class="btn btn-outline-black rounded-0 mt-5">
>         <span class="icon">
>             <i class="fas fa-chevron-left"></i>
>         </span>
>         <span class="text-uppercase">Keep Shopping</span>
>     </a>
> {% endif %}

The bag still needs to be resolved. If a product is added to the bag, the Keep Shopping link returns the user to the home page.
