This commit introduces a comprehensive implementation and refactoring of
the container engine module. Key enhancements include the addition of
abstract classes and the implementation of container engines.
New features:
- Developed `DockerEngine` and `PodmanEngine` classes, deriving from
`AbstractContainerEngine` to provide modular functionality.
- Added a CLI `--container-runtime` option, allowing users to select
their preferred runtime, defaulting to Docker if unspecified.
- Introduced a `container_runtime` property in
`DocMachine::Build::Config` for improved runtime management.
Refactoring:
- Refactored code to replace hardcoded Docker commands with method calls
to `AbstractContainerEngine`, promoting code reuse and abstraction.
