Removing Anserini

[DelaramRajaei]

This is the issue where we log the updates on Anserini and replace it with Pyserini, focusing specifically on the RelevanceFeedback refiner. Since we've shifted from Anserini to Pyserini, one possible solution is to use the SimpleSearcher from Pyserini. However, there are challenges with multiprocessing (mp) since it is deprecated, and the library suggests using Lucene. Unfortunately, I haven't found a similar method in the library.

Here is the link to the issue regarding the recent information on this matter : link

As a quick update, following the meeting with @hosseinfani, we've agreed to revise the code by incorporating sklearn.feature_extraction.text.TfidfVectorizer.
