feat(python): Add optional strict parameter to rename

[Vincenthays]

Maybe it would be better to implement this on the Rust side to keep the api consistent between Rust and Python. Let me know if you want this, I think I can do it.

Yes, this should be implemented in rust.

There were discussions on wether drop should silently no-op or raise https://github.com/pola-rs/polars/issues/11913. I think the discussion was not concluded. Should this change be part of a larger series of canonization of the no-op vs raise?

Also, you're missing a dot at the end of the strict docstring.

I'll close this as the PR is somewhat outdated and there is no matching accepted issue. Let's discuss the merits of adding a non-strict rename in an issue first, and if we agree, the PR can be rebased and re-opened.
