Script does not add the repo if both v3 and v4 are not supported

[jacklul]

On platform which does not suport v3 or v4 the script only installs the keyring, mirrorlists and your pacman fork packages then exits saying v3 is not supported.

One could assume the script will add just the cachyos repository per manual instructions on the wiki page but it does not, because in that case what would be the point of installing the packages if repository isn't added to the config?

Generally repos were/is not seen(value of v1 repo is generally for kernels and distro specific packages) for people to add on machines with cpus older than haswell.

Anyways support for that will be added soon. thanks for report
