Single binary claim is inaccurate

[jart]

On the website it's claimed that zola comes as a single binary. But the project distributes three separate binaries for Linux, WIndows, and Macintosh. Therefore if I use multiple operating systems I need to download multiple binaries.

Consider using https://github.com/jart/cosmopolitan otherwise you may want to update the claim wording to be something like "you only need a single binary on your system"
