📄 Description

This commit introduces several improvements for ARM/M1 support:

Default Container Architecture to Host: act now attempts to detect the host's Docker OS/architecture (e.g., linux/arm64) and uses this as the default for running containers if the --container-architecture flag is not specified. This simplifies usage for you on ARM-based systems like Apple Silicon, allowing act to use native ARM images more seamlessly.
Enhanced CI for linux/arm64: The test-linux job within the checks.yml CI workflow has been updated to include linux/arm64 in its test matrix. This ensures that tests are executed natively on both amd64 and arm64 for Linux, improving test coverage for ARM platforms.
Updated Documentation: The README.md has been updated to:
- Explain the new default container architecture behavior.
- Provide clearer guidance for you on ARM/M1 systems.
- Document the --container-architecture flag.
Removed Outdated M1 Warning: The specific warning message previously displayed to M1 users when no container architecture was specified has been removed from cmd/root.go. This warning is now redundant due to the new default behavior and comprehensive documentation.

These changes aim to provide a better experience on ARM architectures and ensure more robust testing for these platforms.
