chore: update makefile structure and functionality (#3000)

* Updates and changes to the Makefile:

1. Added removal of `frontend` directory inside `src/backend/base/langflow/` and `build` directory inside `src/frontend/` to the `clean_npm_cache` target.
2. Added descriptive comments for the `build_and_install`, `build_and_run`, `fix_codespell`, `setup_poetry`, `unit_tests`, `integration_tests`, and `tests_frontend` targets.

Looking forward to your feedback.

* Improvements: Structure and Functionality Improvements

- Reorganized commands to facilitate understanding of the structure
- Enhanced check_tools to detect the Python version
- Added a multi-environment script to support check_tools
- make init now builds the frontend and runs the application
- Aesthetic improvements in output messages

TO-DO:
- Reorganize container-related commands
- Reorganize other miscellaneous utilities
- Document usage in the application docs
- Prepare the dev environment following the maintainers' recommended practices

* Removed pre-commit as it is no longer used.

* Restored 'patch' command in Makefile, it updates the 'pyproject.toml' with the new project version.
