Add new test methods to TestClass for various parameter types and update documentation

- Introduced `testMethodNoType` with mixed parameter types.
- Added `testMethodWithWrongType` to validate error handling for incorrect parameter types.
- Updated documentation in `MethodMustReturnTypeRule` to clarify checks performed on method signatures.
