feat: Automate process for updating package.json

[Cyber-Syntax]

I am frustrated to update package.json after every new app I started to use. It would be better to have a function to update the config by checking the dnf package manager current installed packages and updating the config file.

• Basic function can be check dnf and add it the temp-packages.json and then compare the two files and add the only new apps.
• Add a function to check the current installed packages for dnf and flatpak.
  • We can use the dnf list installed command to get the list of installed packages and then compare it with the temp-packages.json file. If there are any new packages, we can add them to the config file with new-packages: and list them in the same format as the packages.json file use.

Maybe a remove section to remove the packages that are not used anymore in the package.json file.
