Add tutorial: How to setup github workflow to build exec and publish it

[srghma]

I have a project https://github.com/srghma/purs-utils/

I want to build execs for windows, macos, linux and release them (just like purescript is doing https://github.com/purescript/purescript/releases)

How to do it?

Would be good to have a tutorial at https://input-output-hk.github.io/haskell.nix/tutorials/
