Fix typo in documentation

[tkin91e55]

May remind user the template overriding order somewhere in documentation.
For example:

1. use the Template filesystem loader to prioritize the extra template loading rather than App dirs

TEMPLATES = [
    {
        "BACKEND": "django.template.backends.django.DjangoTemplates",
        "DIRS": [
            BASE_DIR / "base" / "templates",  # base/ is not an app, extra dir for FileSystemTemplate
        ],
        # ....
    },
]

2. Mind the app load order which decide the template loaded

INSTALLED_APPS=
[
  'myblog', # go before
  # ....
  'django_comments_xtd'
]

# instead of
INSTALLED_APPS=
[
  'django_comments_xtd',
   # ....
  'myblog', # go before
]

Refer to django-contrib-comments, https://github.com/django/django-contrib-comments/blob/2.2.0/django_comments/templatetags/comments.py#L184

if the app specific template search is supported, it would be nicer.

Thanks for the fix, @tkin91e55.

And yes, I think it makes sense to add a reminder of the template loading order in the docs.
Maybe a new first section in the templates.rst page. And linking to it from the tutorial.rst, on every mention to the template loading order.

I can add it, but if you prefer it, you can add it in this very PR too.
