Minor adjustment in the ReadMe: Switch the order of the packages in the install command?

[hced]

The ReadMe gives a quick copy/pastable install command: yay -S soulver-cpp-git swift-bin-6.1. This didn't work for me, but the other way around worked: yay -S swift-bin-6.1 soulver-cpp-git, since the cpp relies on swift.

For convenience, maybe change the order on how it's written?
