Allow to fail the CI without adding any labels

[VincentLanglet]

Hi @jcw- @thehanimo

I wanted to use the following configuration

{
  "CHECKS": {
    "prefixes": ["fix: ", "feat: "]
  }
}

To check the PR but not adding any label
Just failing the CI

This is currently not supported, what do you think about adding it ?
