Remove "Wrapper" abstract class

[henriquemoody]

With PHP's promoted properties, there is little reason to have an abstract class that only provides a constructor and a proxy method. The greater part of the classes that extended Wrapper had their own implementation of evaluate(), hence it made very little sense to keep Wrapper in the codebase.

Pull request overview

This PR removes the Wrapper abstract class from the codebase, replacing it with direct implementations in the validators that previously extended it. With PHP's promoted properties, the minimal functionality provided by Wrapper (constructor and evaluate() proxy) is no longer necessary, especially since most extending classes had their own evaluate() implementations.

Changes:

• Removed the Wrapper abstract class and its test files
• Updated 13 validator classes to implement Validator interface directly instead of extending Wrapper
• Updated migration documentation to remove Wrapper from the list of available base classes
