[Core] Warn when cucumber.options is used

[mpkorstanje]

🤔 What's changed?

In #1779 we deprecated and removed cucumber.options. Unfortunately there are a slew of outdated tutorials still in existence. And this outdated knowledge creates a slow trickle of questions on StackOverflow. It would be nice if we can stop this waste of everyone's time.

Fixes: #2673
