Update the Hack Code of Conduct

[loleg]

Dribdat out of the box suggests using the Hack Code of Conduct in events. It has been a few years since https://hackcodeofconduct.org/ was updated, the page itself is full of 'test' users and is not really attractive, readable, internationalised, etc. The GitHub repo has been archived. Let's find out if there is already an initiative (a fork?) to update it.

Meanwhile, we have adopted the Contributor Covenant as Code of Conduct for the Dribdat project itself.

The Conf Code of Conduct by comparison, has been translated to many languages and is reasonably actively maintained. There are some interesting aspects to it like the "this code is a template" that I really like.
