Rollup merge of rust-lang#122072 - KonradHoeffner:patch-1, r=cuviper

Refer to "slice" instead of "vector" in Ord and PartialOrd trait impl of slices

The trait implementation comments of Ord and PartialOrd for slice incorrectly mention "vectors" instead of "slices".
This PR fixes those two comments as requested in rust-lang#122071.
