SysUp v0.0.1

Hello there! 👋

This is my first release

This script automates the process of updating your Linux system.
If you have multiple package managers like Flatpak, Snap, etc., they will also check for updates.
If your package manager isn't detected, you can easily add it by editing the script.
So far, I've added support for the following managers:

• apt
• aptitude
• brew
• dnf
• flatpak
• fwupdmgr
• pacman
• snap
• yay
• yum
• zypper

As before, if any command is implemented incorrectly, it can be easily corrected in the script and open an issue or a pull request with the correct commands.
This script was tested in Debian WSL (with apt and aptitude) and Manjaro (with flatpak and pacman).
