🤔 What's changed?

When scanning classes, we avoid scanning anonymous classes, because they cannot contain cucumber steps and hooks.

⚡️ What's your motivation?

Contributes to #3141.

Anonymous classes are non-public classes so their methods will not be scanned by the MethodScanner, but the class will still be loaded. By avoiding scanning the anonymous classes earlier in the ClasspathScanner, we avoid loading the class. Well, the class may be loaded by other part of the application, but at least this will not be Cucumber's fault.
