Rollup merge of #136775 - robertbastian:patch-2, r=Amanieu
Update `String::from_raw_parts` safety requirements These have become out of sync with `Vec::from_raw_part`'s safety requirements, and are likely to diverge again. I think it's safest to just point at `Vec`'s requirements. https://github.com/rust-lang/rust/issues/119206#issuecomment-2180116680
