Fix typo in docs for slice::split_once, slice::rsplit_once

This fixes a typo in the doc comments for these methods, which I tripped over while reading the docs: "If any matching elements are **resent** in the slice [...]", which is presumably meant to read **present**.

I mentioned this in rust-lang#112811, the tracking issue for `slice_split_once`, and was encouraged to open a PR.
