In `README.md`, There's a typo at [this highlighted link](https://github.com/jazzband/django-admin-sortable#:~:text=in%20additional%20ORM%20%22-,filer_args,-%22%20as%20a%20list), where it says "filer_args" instead of "filter_args". It's evident that this is a typo, since in the code snippet below the link, `filter_args` is used.
