Update rename.md

[brad-burch]

Noticed the documentation example fails, which is probably a bug (it should probably be able to take a list or a record). But this example is functionally equivalent, except renaming the second column for clarity in targeting columns besides the first.

I'm not following. This works

❯ [[a, b, c]; [1, 2, 3]] | rename --column { a: ham }
╭#┬ham┬b┬c╮
│0│  1│2│3│
╰─┴───┴─┴─╯

This does not work

[[a, b, c]; [1, 2, 3]] | rename --column [ b, ham ]

You must be using an older version of nushell. I believe it was recently changed.

I apologize, on v0.85 and trying to learn NuShell and I love it! Updated to v0.86 and it is indeed fixed (you guys move fast). Also noticed you generate these, so I will look over in the Rust logic for these examples. Thank you!
