Incorrect detection of string constant overuse (WPS226)

[smac89]

What's wrong

String usage is detecting strings used inside list of dictionaries as being overused. For example in a django project, the following configuration will trigger the rule violation on NAME:

AUTH_PASSWORD_VALIDATORS = (
    {
        "NAME": "django.contrib.auth.password_validation.UserAttributeSimilarityValidator",
    },
    {
        "NAME": "django.contrib.auth.password_validation.MinimumLengthValidator",
    },
    {
        "NAME": "django.contrib.auth.password_validation.CommonPasswordValidator",
    },
    {
        "NAME": "django.contrib.auth.password_validation.NumericPasswordValidator",
    },
)

---

Additionally, there is a documentation mismatch. The docs for max-string-usages here says the default is 5, but the documentation for the rule says it is 3 (which is also what I saw)

How it should be

Dictionary keys should not count towards string overuse

Hope you don't mind pipenv graph, as I don't use pip directly.

Oh, sorry!

Can you please make a PR with the fix? It should be 3 indeed.

Yeap. Here's what's wrong:
