How to use the `--ast` properly?

Based on --help, I can see there's a standalone --ast flag. I have attempted to use it and it throws an error message:

$ bin/natalie --ast examples/hello.rb

Can you please tell me what I'm doing wrong exactly here?

This is borked currently as we transition to using Prism nodes in pass1. I'll leave this open as a bug issue until it's fixed.

Ah phew... 😆 I thought I broke something by mistake and didn't know what it was or where to look!

This should be fixed now!
