Update desktop build instructions fixes #2792

This is based on what I had to do to get the desktop app running, as per the advice in https://github.com/vector-im/riot-web/issues/2792. I am not familiar with `npm`, so please change this pull request if there is a more appropriate way of achieving the same result.
