chore: update configuration files and enhance dependency management

- Added new entries to `.pre-commit-config.yaml`, `cmake-format.yaml`, and `.github/dependabot.yml` to improve code quality checks and dependency updates.
- Enhanced GitHub Actions workflows by adding new steps for testing and build retention.
- Introduced support for the nlohmann_json library in CMake, allowing for conditional inclusion based on the `YAZE_ENABLE_JSON` option.
- Updated CMake configurations to streamline SDL2 and gRPC integration, ensuring proper linking and target management.

Benefits:
- Improves code quality and consistency through automated checks and formatting.
- Enhances dependency management and build reliability across platforms.
- Provides flexibility for users to enable optional features, improving overall functionality.
