Type ModelAdmin.fieldsets 'description' option to support gettext_lazy

[flaeppe]

I have made things!

Quite a bit far down into ModelAdmin.fieldsets, the "description" value should support being gettext_lazy

i.e. the following should type check

from django.utils.translation import gettext_lazy
...


class MyModelAdmin(ModelAdmin):
    fieldsets = (
        (
            gettext_lazy("group 1 header"),
            {"description": gettext_lazy("description"), "fields": ("f1", "f2")},
        ),
        (
            gettext_lazy("group 2 header"),
            {"fields": ("f3", "f4")},
        ),
    )
