rustdoc: Update doc comment for splitn_mut to include mutable in the … The doc comment for [splitn](https://github.com/rust-lang/rust/blob/master/library/core/src/slice/mod.rs#L2051:L2056) is the exact same as the comment for [splitn_mut](https://github.com/rust-lang/rust/blob/master/library/core/src/slice/mod.rs#L2079:L2084). The doc comment for `splitn_mut` should instead say it's working on a mutable subslice. |
