Description of change

According to this https://redis-py.readthedocs.io/en/stable/examples/search_vector_similarity_examples.html#KNN-Queries, there is a missmatch between the type hints of the method and the actual expected usage. This makes mypy complain when being used

@JoanFM Can you please fix the linters failure?

Hey @dvora-h,

It would be hard to do this for a couple of weeks that I will not have my laptop with me.

Also, I do not see how to fix this, as the lines related are not even touched by me.

Would it be possible for you or someone else to maybe fix it on a branch and do a PR to my fork perhaps?

@JoanFM Thanks for your response, no problem, I will push a fix to your branch.
