Dont expose extract_probability as C API parameter

[RomanValov]

Presence of extract_probability parameter on PARAMS_SCHEMA dict causes a confusion
because docs say PARAMS_SCHEMA parameters should be recognized on Model.__init__
and passed to underlying whisper.cpp library.
But attempts to pass extract_probability to Model.__init__ cause segfaults.
Indeed extract_probability handled purely on python side.

Good catch @RomanValov. You're right, extract_probability is handled entirely on the Python side, so having it inside PARAMS_SCHEMA is misleading and can definitely cause confusion given the current docs/behavior.

I just ran CI, and it's currently failing. There also appear to be some merge conflicts since another PR was merged into main recently.

Could you please rebase onto the latest main, resolve any conflicts, and fix the syntax error?

Thanks!

I have rebased it and fixed the syntax. Should be passing tests now

Sounds Good!
Thanks @RomanValov for the contribution :)
