RandomSample on a list returns one item.

Again an exmple from https://www.wolfram.com/language/elementary-introduction/2nd-ed/30-rearranging-lists.html

RandomSample[Range[10]]

always produces one item when it should produce more. A revised version of chapter 30 will go out with the next docker update (which will not be done with the 5.0.0 release but probably a week later.)
