NIT: I'm not sure if every script supports every "officially" supported manager, If not, we need to fix this.

What if a different package manager is added? This PR offers no improvements to maintainability or anything of the sort, and only offers the potential for issues to come up in the future.

[jeevithakannan2]

If another package manager is added it will be handled anyway. For example, if we are adding nix then we will be adding nix to most of the scripts. If nix cannot be used for a specific script then it will be handled as unsupported. Having extra bloat that will not be reached is useless anyway.

Yes. And this PR proposes the removal of that error handling.

Having extra bloat that cannot be reached is useless anyway 🤷🏻‍♂️
We can always add them back to scripts that don't support packagers later

They cannot be reached assuming all package managers supported by linutil are supported by the script. I've just stated a way in which that condition could be broken. Your idea of adding this code back in the case of any changes illustrates why removing it is a poor decision to begin with.
