Raise error when using o>| pipe (#13323)

# Description
From the feedbacks from @amtoine , it's good to make nushell shows error
for `o>|` syntax.

# User-Facing Changes
## Before
```nushell
'foo' o>| print                                                                                                                                                                                                                     07/09/2024 06:44:23 AM
Error: nu::parser::parse_mismatch

  × Parse mismatch during operation.
   ╭─[entry #6:1:9]
 1 │ 'foo' o>| print
   ·         ┬
   ·         ╰── expected redirection target
```

## After
```nushell
'foo' o>| print                                                                                                                                                                                                                     07/09/2024 06:47:26 AM
