feat(template): ✨ add method to skip documentation for specific methods

- Add `skipMethod` method to `IJavadocDocTemplate` interface
- Implement method to filter out methods that should not be documented
- Update method processing logic to use the new skipMethod check
- Optimize list initialization in methodMap
