django-polymorphic==4.5.0 dependancy version bump causes new migrations

[maddrum]

Upon makemigrations message is received

Migrations for 'filer':
  .local/lib/python3.11/site-packages/filer/migrations/0019_alter_file_folder_alter_file_owner_and_more.py
    - Alter field folder on file
    - Alter field owner on file
    - Alter field polymorphic_ctype on file
    - Alter field file_ptr on image

caused by a new version of django-polymorphic==4.5.0
works fine with django-polymorphic==4.4.1

@maddrum Thanks for pointing this out!

@maddrum For me these migrations are created over and over again each time I run makemigrations. Can you check this?
