Rollup merge of #47125 - daboross:patch-3, r=estebank
Mention SliceConcatExt's stability in its docs Just saw someone in IRC mention there being no stable way to join string slices! It isn't entirely clear from the rust documentation that `SliceConcatExt` is usable. While this is mentioned in https://doc.rust-lang.org/std/prelude/, the trait has nothing to indicate that it's currently usable if found via a documentation search. The wording on this could probably be improved, but I'm hoping its better than nothing.
