This pull request introduces several important updates in preparation for version 14.0.0, including support for Docker Compose v2, removal of Python 3.7 support, and modernization of some dependencies and internal APIs. The changes also update the GitHub Actions test matrix and streamline Docker Compose integration.

Key changes:

Docker Compose v2 support and related improvements:

• Updated Docker Compose integration to use the docker compose CLI (instead of the Python module or docker-compose), enabling support for Docker Compose v2. This includes changing how compose processes are run and how container service names are extracted, ensuring compatibility across Compose versions. [1] [2] [3]
• Removed the docker-compose<2 dependency and related comments from setup.py, reflecting the move to Compose v2 and the CLI approach.

Python version and dependency updates:

• Dropped support for Python 3.7 and updated the GitHub Actions test matrix to test only supported Python versions (3.8+), and updated the tested Ubuntu versions. [1] [2]

Dependency and import modernization:

• Replaced deprecated pkg_resources usage with importlib.metadata for version retrieval in __init__.py.
• Switched from pkg_resources.parse_version to packaging.version.parse for version parsing in config.py.

Changelog:

• Added a new section for v14.0.0 in CHANGELOG.md documenting Docker Compose v2 support and Python 3.7 deprecation.
