restore previous logic with match arms

[ikripaka]

It seems we currently have a limitation where we can't perfectly preserve the original order of the match arms
Right now, the parser provides them in a fixed order (we typically receive the negative option first)
I’ve added a temporary fix for this, though ideally, we'd want to address it in the parser later
For now, the behaviour will be:

• enums are formatted as the user wrote
• true and then false match arms stay the same
• false and true match arms reordered to true and false
• Some and None match arms stay the same
• None and Some match arms reordered to Some and None
• Left and Right match arms stay the same
• Right and Left match arms reordered to Left and Right
