Updated googletest version to v1.6.0 (#2031)

Failure occurred due to the deprecation of support for CMake versions
earlier than 3.10. Since the Ubuntu GitHub runner uses CMake 3.31.6,
which no longer supports versions prior to 3.10 in many cases, our
pinned version of GoogleTest needed an update. Additionally, other
dependencies, such as JSON and JSON Schema Validators, were updated to
the minimum compatible versions, with 3.5 being the lowest supported.


https://cmake.org/cmake/help/latest/release/3.31.html#deprecated-and-removed-features

The change includes:
- Pin googletest to latest v1.16.0
- yaml-cpp patch update `cmake_minimum_required(VERSION 3.10)`
- json patch update `cmake_minimum_required(VERSION 3.10)`
- json-schema-validator patch update `cmake_minimum_required(VERSION
3.10)`
- Updated ubuntu-20.04 to ubuntu-22.04. **GitHub Actions is deprecating
the ubuntu-20.04 runner**.
