Subject: [PATCH] feat(cmake): update yaml-cpp dependency handling for CMake
 compatibility

- Modified the CMake configuration for yaml-cpp to use version 0.8.0 with an inline patch, ensuring compatibility with CMake 3.31+.
- Implemented a manual population and patching process to adjust the minimum required CMake version in the yaml-cpp CMakeLists.txt, enhancing build reliability.

Benefits:
- Improved compatibility with newer CMake versions.
- Streamlined dependency management for yaml-cpp.
