[FEAT] Ability to add other package managers via config files

[dnkmmr69420]

Before requesting a new feature

• A lot of features are not enabled by default. Please try fastfetch --list-modules and fastfetch -c all.jsonc to see if it has been supported
• Fastfetch supports Command module, which can be used to grab output from a custom shell script. Please check if it fits your needs

Wanted features:

I would like to add other package managers using configs. There would be at least these two parts for the config, the command that is ran and the display name (what it displays in the fastfetch)

Motivation:

I would find it useful for it to count packages in containers. I have a very specific use for my own project Brew Container where it would run cbrew to count the packages in my homebrew container

If you are unable to get this implemwnted, can you at least add cbrew with the option to disable it?

I'm not sure I get it correctly. Do you want to display the package count for your project cbrew in fastfetch? In this case I think Command module is enough to use.

Will I need to modify source code?
