[Sylius Hackathon - Paris Mars 2025] Add FrankenPHP build

[Prometee]

This pull request introduces a comprehensive CI workflow for building and testing FrankenPHP Docker images for Sylius, along with necessary configurations and Dockerfiles. The key changes include the addition of a GitHub Actions workflow, Dockerfile configurations for different environments, and Bazel build and test configurations.

GitHub Actions Workflow:

• Added .github/workflows/sylius-frankenphp.yml to define a CI pipeline for building and testing FrankenPHP Docker images with different PHP versions and distributions. This includes steps for setting up QEMU, caching Docker layers, building multi-platform images, and running Bazel tests.

Dockerfile Configurations:

• Created frankenphp/Dockerfile with multi-stage builds for base, development, and production FrankenPHP images. This includes installing necessary PHP extensions, setting up Composer, and defining health checks and commands for different environments.

Bazel Build and Test:

• Updated frankenphp/BUILD to include Bazel build and test configurations for different architectures and PHP versions. This leverages container_import and container_test rules from Bazel's Docker rules.

Configuration Files:

• Added configuration files for different environments:
  • frankenphp/conf.d/app.ini for general settings.
  • frankenphp/conf.d/app-cli.ini for CLI-specific settings.
  • frankenphp/conf.d/app.dev.ini for development environment settings with Xdebug.
  • frankenphp/conf.d/app.prod.ini for production environment settings.

Test Data:

• Added test data files for different PHP versions and architectures to validate the Docker images using Bazel's container_test. These files define tests for file existence, permissions, and command outputs. [1] [2] [3] [4]
