Remove ImageField from the NOT_NULL_TRUE_FIELDS.

[mrswats]

ImageField is not a CharField and therefore it should not be checked by DJ01.

@rocioar Should FileField be removed this way as well?

[rocioar]

Yes, good call.

FileField/ImageField are not a CharField, but they behave the same.

and in https://docs.djangoproject.com/en/3.1/ref/models/fields/#filefield

FileField instances are created in your database as varchar columns with a default max length of 100 characters. As with other fields, you can change the maximum length using the max_length argument.
