Superpoint imports fix

[zucchini-nlp]

What does this PR do?

I have been seeing this errors for a few days (when make quality) and seems like there is no PR fixing it. I decided to make it a separate PR, to merge quickly independently of other changes.

That's a bit weird, ci's are green on main. Locally I don't have an issue so most probably a version of ruff?

I noticed now that it does not fail in every make quality. Guess that depends on what local changes were made 🤔

The bug here is that the import is done from incorrect place, because the requires_backend should be imported from utils. It is already done so for all image processors in library. I am not sure how the Superpoint model tests passed when adding the model, but currently trying to get the processor as below fails in main

processor = AutoImageProcessor.from_pretrained("magic-leap-community/superpoint")
