Use commitlint

I believe that using commitlint is a nice tool to create short, descriptive commit messages. Moreover, we could later create (release) changelogs from them, once we learn to follow the rules.

This my commitlint.config.json in my other project. Again, we can discuss individual configs; nothing is built into stone.

commitlint.config.json

const {readdirSync} = require('fs')
