 (#15248)

solution for #15242

adds "And"

```
~/Projects/nushell> [[a, b]; [1., 2.], [3.,3.], [4., 6.]] | polars into-df | polars filter (((polars col a) > 2) and ((polars col b) < 5))
╭───┬──────┬──────╮
│ # │  a   │  b   │
├───┼──────┼──────┤
│ 0 │ 3.00 │ 3.00 │
╰───┴──────┴──────╯
```

adds "Or"

```
~/Projects/nushell> [[a, b]; [1., 2.], [3.,3.], [4., 6.]] | polars into-df | polars filter (((polars col a) > 7) or ((polars col b) > 5))
╭───┬──────┬──────╮
│ # │  a   │  b   │
├───┼──────┼──────┤
│ 0 │ 4.00 │ 6.00 │
╰───┴──────┴──────╯
```

but not (yet) xor because polars doesn't have a direct expression for
logical_xor

```
~/Projects/nushell> [[a, b]; [1., 2.], [3.,3.], [4., 6.]] | polars into-df | polars filter (((polars col a) > 7) xor ((polars col b) > 5))
Error: nu::shell::operator_unsupported_type

  × The 'xor' operator does not work on values of type 'NuExpression'.
