The mailing list obsolete

[mpkorstanje]

🤔 What's the problem you've observed?

Hey folks, the README says:

If you need to ask a question, don't open a ticket on GitHub! Please post your question on the Cucumber discussion group instead, prefixing the title with [CPP].

But we don't have a mailing list anymore so we get people creating issues anyway (#302).

✨ Do you have a proposal for making it better?

We do have Github Discussions https://github.com/orgs/cucumber/discussions, so it might be worth to reference that.

📚 Any additional context?
