Change print to logging in index

[Samoed]

I also wanted to add T20 to ruff rules, but in utils folder a lot of prints, so I'm not sure how to deal with them

You will need to update the docstrings in order to make the tests pass I think so :)

I've updated test. One of the tests failing due to HF rate limits

Yeah, it's a pain these days, have to relaunch a few times for them to run...

You mean the utils of stanford-nlp plaid index? It should not really be an issue because the index will slowly be deprecated to use fast-plaid, but we might want to clean logging still

Edit:
Tests are passing, we can merge except if you want to handle utils right now

Edit2: I merged so we can release the new version, tell me if this was required for something
