Error out when Select gets same row (#8200) ...

# Description
Fixes #8145, by disallowing any rows that are duplicated.

```
❯ ls | select 0 0
Error: 
  × Select only allows unique rows
   ╭─[entry #1:1:1]
 1 │ ls | select 0 0
   ·               ┬
   ·               ╰── duplicated row
   ╰────

```
