✨ Add generator script for linux

[axel-eck]

This pull request adds a new script, generate.sh, to automate the setup of a new C++ project with options for using CMake and Conan. The script includes functions for user interaction, project directory setup, and optional build script generation.

Key changes include:

User Interaction Functions:

• Added functions print_check, print_cross, and print_question_mark to display status symbols.
• Implemented ask and prompt functions to handle user input and selection.

Project Setup:

• Created a function to generate a new C++ project directory with CMakeLists.txt and optional conanfile.txt based on user input.
• Added logic to handle Conan installation and configuration if selected by the user.

Build Script Generation:

• Included an option to generate build scripts for Linux and Windows environments.
