Rollup merge of #62634 - llogiq:uninit-array-docs, r=RalfJung

Less unsafe in the array example of MaybeUninit docs

I believe this is an acceptable way to initialize elements of `[MaybeUninit<T>; _]` arrays. Miri agrees. Conceptually, we are working at the array level, above the `MaybeUninit`, and as we are replacing it wholesale, this should pose no problem to soundness. And the code is easier to read.
