Auto merge of #56463 - ljedrz:slice_concat_join, r=nikic
slice: tweak concat & join
- use `sum` instead of `fold` (readability)
- adjust the capacity for `join` - the number of separators is `n - 1`, not `n`; proof:
```
fn main() {
let a = [[1, 2], [4, 5]];
let v = a.join(&3);
assert_ne!(v.len(), v.capacity()); // len is 5, capacity is 6
}
```
