Enhance unstable with 8.0+ improvements and testing infrastructure (#463)

This commit consolidates multiple improvements to the Redis Docker library:

**Major Infrastructure Changes:**
- Restructure repository by moving legacy templating scripts to dedicated directory
- Add new simplified Dockerfile structure for Alpine and Debian variants
- Introduce comprehensive entrypoint testing framework with shunit2

**Docker Image Improvements:**
- Bump Alpine base image from 3.21 to 3.22
- Add support for Rust compilation with clang-static, llvm-dev, ncurses-dev packages
- Set RUST_DYN_CRT=1 environment variable for dynamic runtime linking
- Fix file permissions for Redis configuration files
- Preserve apk package management tools in final image
- Use setpriv instead of gosu for privilege dropping in entrypoint
- Improve entrypoint script robustness and remove eval usage

**CI/CD Enhancements:**
- Add GitHub Actions workflow for pre-merge testing
- Implement ARM64 support in build and test actions
- Configure fail-fast: false for better parallel testing
- Fix PR workflow to test merge commits instead of head commits
- Add callable workflow options for flexibility

**Testing & Quality:**
- Introduce comprehensive entrypoint testing suite
- Add container initialization wait logic
- Implement version-specific test cases for unstable builds
- Add .dockerignore for optimized build context

**Version Management:**
- Cherry-pick Redis 8.2 M01 improvements while maintaining unstable branch builds
- Ensure compatibility with Redis 8.0+ features
- Maintain backward compatibility with existing configurations
