This script performs an auto-installation of my zsh settings, also installing oh my zsh and another useful plugins inside it

This script has only been tested on Ubuntu 20.04 (native and through WSL), so it should be modified (the package installation commands) in order to support other distributions.

Notes:

• If you find any problem after running the script, you can just go back to bash by using the next command: chsh -s /bin/bash
• To reconfigure your shell theme, run: p10k configure
