Exits with code 0 after parse error

[cdfa]

Hi, I'm getting a 0 exit code when trying to lint files with parse errors. Failing to parse seems like a failure to me, so I think it should exit with something else.

I'm on commit 01ed700247e159db0ed8c5e2cff1fed9af582946

👍 I am using nix-linter as a part of CI pipeline for my home-manager configuration and I would rather expect it to fail if there is a parsing error
