make reject support list input directly (#11024)

Browse source 
# Description
Fixes: #10895 

It's because `reject` and `select` command can't handle list of CellPath
input directly.
After this pr, the following should be ok:
```nushell
❯ [{'a': 1, 'b': 2, 'c': 3}, {'a': 1, 'b': 2, 'c': 3}] | reject ['a', 'b']
╭───┬───╮
│ # │ c │
├───┼───┤
│ 0 │ 3 │
│ 1 │ 3 │
╰───┴───╯
❯ [{'a': 1, 'b': 2, 'c': 3}, {'a': 1, 'b': 2, 'c': 3}] | select ['a', 'b']
╭───┬───┬───╮
│ # │ a │ b │
├───┼───┼───┤
│ 0 │ 1 │ 2 │
│ 1 │ 1 │ 2 │
╰───┴───┴───╯
```
