Minimum Swift version is now 5.4

Because of `@resultBuilder`, the minimum Swift version is now 5.4. So I think that means that Package.swift should be updated? Specifically the first line: `swift-tools-version:5.1`.

Do you have to do that manually or can you have it regenerated from the toolchain in a predictable manner?

I think it has to be done manually.

Should be better now.
