For `Void` element AsyncSequence types it might be nice to have a `waitForAll() async rethrows` similar to TaskGroup

[phausler]

extension AsyncSequence where Element == Void {
    func waitForAll() async rethrows {
        for try await _ in self { }
    }
}

Hey @phausler I wanted to work on this issue but can you explain to me in more detail what exactly is the problem to fully understand what to do.
