[flake8-django] DJ001 is not raised for fields which has unique=True

[kiddten]

class Product(models.Model):
    test = models.CharField(null=True, blank=True, max_length=255)

is correct

DJ001 Avoid using null=True on string-based fields such as CharField

but

class Product(models.Model):
    test = models.CharField(null=True, blank=True, max_length=255, unique=True)

All checks passed!

gives no warning

if blank_key && unique_key {

See https://docs.djangoproject.com/en/5.1/ref/models/fields/#null for the rationale. This is indeed expected behavior
