* build(docker): refactor detection of OS

This commit also adds support for RHEL distros

* build(install): use functions for installing dependencies

* feat(install): enhance installation script with Docker Compose version check and refactor package installation

- Refactored the installation script to include a Docker Compose version check, ensuring compatibility with version 2.0.0 or higher.
- Consolidated package installation functions into a generic install_package function to streamline the installation process for various packages like nano, curl, and make.
- Improved error handling and logging for package installations and Docker setup.

* feat(install): enhance Docker and Docker Compose checks in installation script

- Added functions to check Docker and Docker Compose installations, including version checks and guidance for installation or upgrade if necessary.
- Removed automatic installation of Docker and Docker Compose, replacing it with user guidance for manual installation.
- Updated the installation script to ensure Docker is installed and running before proceeding.

* fix: improve Docker installation checks and update Makefile

- Enhanced the Docker installation script to repeatedly prompt the user until a valid choice is made.
- Updated the Makefile to include checks for Docker Compose installation and user permissions, ensuring the user is in the docker group or running as root.

* build(install): move pre-req check after env check

* build(install): specify color meaning and change some

* build(install): provide more specific error information
