Error while passing gettext_lazy to arguments expecting strings

[hannseman]

Bug report

What's wrong

Errors when passing gettext_lazy strings to parameters expecting strings like verbose_name and help_text on model fields:

error: Argument "verbose_name" to "PositiveBigIntegerField" has incompatible type
"_StrPromise"; expected "Optional[str]"  [arg-type]
            null=True, blank=True, verbose_name=_("number")

(where _ is defined as from django.utils.translation import gettext_lazy as _)

This was introduced in #689

How is that should be

_StrPromise should be able to be passed as a str.
