fix(datafusion-cli): solve row count bug addingsaturating_add to prevent potential overflow (#20185)

Currently `print_options::MaxRows::Unlimited` basically always panics
with `attempt to add with overflow`, because we are summing `usize::MAX`
with a positive number.

`saturating_add` solves this issue

# MRE

```rs
fn main() {
    let max = usize::MAX;
    println!("max: {}", max);
    let max = max + 1;
    println!("max: {}", max);
}
```
