Documentation on redirect doesn't match behaviour

Note that file redirections are scoped to an expression and apply to all external commands in the expression. In the example below, `out.txt` will contain `hello\nworld`:

> let text = "hello\nworld";
($text | head -n 1; $text | tail -n 1) o> out.txt
hello
> cat out.txt
world
> nu --version
0.112.1

I wouldn't be surprised. Code changes fast around here.
