fix: update Python installation script to require version specification

- Modified the Python installation script to remove the default version assignment and enforce version specification during installation.
- Updated usage instructions to reflect the change from a default version to requiring a user-defined version, improving clarity and preventing installation errors.
- This change enhances the robustness of the installation process by ensuring users explicitly define the Python version they wish to install.
