The pivot user guide doc and API doc are both outdated

Description

The following are outdated:
https://docs.pola.rs/user-guide/transformations/pivot/
https://docs.pola.rs/api/python/stable/reference/dataframe/api/polars.DataFrame.pivot.html

There is no on anymore (now: columns).

It looks like Polars API documentation structure doesn't follow the DRY principle? I indeed learned this principle formally for the first time in your doc ^_^!

The columns parameter of pivot was renamed on in #17095 (see https://github.com/pola-rs/polars/pull/17095/files#diff-50f8a5e1ee71cadef61bbae257a72d6b4549020e76abe947b4ee36ef79d553c6 for the specific change in pivot), so the user guide and API docs are correct.

hi @liufeimath - could you clarify which part is outdated please? looks fine to me but I might have missed something

Thanks for the report, but it seems like you were looking at an old (cached?) version of the docs somehow.

I'll close this - can reopen if you can show us some steps to get to an outdated version of the docs.

Oh got it. I was using an 0.20.x version before and didn't realize that columns was renamed to on in 1.0.0. All good now. Thanks!
