`_DELETE` events not triggered by admin delete batch action

[foucdeg]

The batch action in Django Admin that allows deleting instances (check a few lines in the list and select "delete" in the dropdown menu) does not trigger BEFORE_DELETE and AFTER_DELETE events.

This is understandable, as the action calls .delete() on a queryset and not individual instances. However, I think it might be worth a notice in this library's documentation.

A workaround is to override ModelAdmin.delete_queryset:

class BookAdmin(admin.ModelAdmin):
    def delete_queryset(self, request: HttpRequest, queryset: QuerySet[Book]) -> None:
        # Delete each instance individually to trigger the delete lifecycle hook.
        for instance in queryset:
            instance.delete()

Definitely this is something that has to be in the docs, and it's in the roadmap: #143

Anyway, thanks for reporting it and suggest a workaround!
