Asterisk: add interactive version selection to installer

The install script now fetches available Asterisk versions (Standard, LTS, Certified) from the official website and prompts the user to select which version to install. The download and installation process adapts based on the user's choice. Also updated package management commands from 'apt-get' to 'apt' for consistency.
