Convert tqdm.notebook.tqdm monkey patch function to a class

[alecglen]

📝 Summary

Implements the easier of the two proposed solutions in #4016.

🔍 Description of Changes

tqdm.notebook.tqdm being assigned as a function instead of a class was breaking consumers intending to subclass it. With this update, the patch object's semantics remain unchanged - when called, it parses its inputs and returns a Marimo progress_bar. It's just converted from a function that returns the progress_bar to a subclass of the progress_bar itself.

Before: See example at the bottom of #4016.
