Do not call stty on non-tty
When testing on a non-tty (e.g.: github actions),
either one of these lines produces an error:
```ruby
input.echo = true
ask("question", "y") { |q| q.readline = true }
```
The error is produced by ruby internals:
```bash
echo | rake | cat
......stty: stdin isn't a terminal......
```
This change skips the stty calls if the input is not on a tty, so the
errors will not be produced.
