Remove deprecated

[Philippe-Cholet]

At the same time as #877, I listed our deprecated parts:

Deprecated	Alternative	Comment
Itertools::group_by since 0.13.0	Itertools::chunk_by	Newly deprecated. Do not remove!
unfold since 0.13.0	core::iter::from_fn MSRV ≥ 1.34.0	Newly deprecated. Do not remove!
Itertools::fold1 since 0.10.2	Iterator::reduce MSRV ≥ 1.51.0	Unavailable alternative since MSRV = 1.43.1 Do not remove!
zip since 0.10.4	core::iter::zip MSRV ≥ 1.59.0	Unavailable alternative since MSRV = 1.43.1 Do not remove!
repeat_call since 0.8.0	core::iter::repeat_with MSRV ≥ 1.28.0	Remove?!
Itertools::foreach since 0.8.0	Iterator::for_each MSRV ≥ 1.21.0	Remove?!
Itertools::step since 0.8.0	Iterator::step_by MSRV ≥ 1.28.0	Remove?!
Itertools::map_results since 0.10.0	Itertools::map_ok	Remove?!
Itertools::fold_results since 0.10.0	Itertools::fold_ok	Remove?!

Should we remove repeat_call, Itertools::{foreach, step, map_results, fold_results} (which is what I did here)?
Or when should we?

Note: 0.8.0 and 0.10.0 are resp. 5 and 3 years old.

The list of deprecations is not complete. I used some command line to make the list but it clearly did not do what I expected.

EDIT: It was only missing zip, list updated.

At first, I did not understand why semver-checks passed CI but it's simply because the version was bumped in Cargo.toml to 0.13.0. 🙄

Thanks for this.
