docs: explain minimal sensible config better

[FezVrasta]

I can't understand why commitlint doesn't throw error here?

[marionebl]

Could you paste the content of your commitlint.config.js file?

[FezVrasta]

no content, I guess it may be the problem? 🤔

[marionebl]

Ah okay. commitlint basically does not do anything without configuration:

npm install --save-dev commitlint-config-angular

// commitlint.config.js
module.exports = {
  extends: ['angular']
};

[FezVrasta]

I see, thanks!

[marionebl]

I'd like to keep this open as our docs are not clear enough as it seems.

We probably should warn when there is no config applied at all.
