Fixing RemovedInDjango30Warnings
**Background:** The `django.shortcuts` method `render_to_response` became deprecated in [Django 1.3](https://docs.djangoproject.com/en/3.0/releases/1.3/), when `render` was introduced.
Per the documentation:
> render() is the same as a call to render_to_response() with a context_instance argument that forces the use of a RequestContext.
Both return an `HttpResponse` object.
**Context:** We changed two statements: An import line and the call to the method, adding explicit parameter names to improve readability.
**Before:**
```
from django.shortcuts import get_object_or_404, render_to_response
...
return render_to_response("teams/teams.html", context)
```
**After**
```
from django.shortcuts import get_object_or_404, render
...
return render(
request=request,
template_name="teams/teams.html",
context=context
)
```
