Very nice action, certainly needed!

There's one con, though - it's missing the build process. While it will be enough to deploy simpler plugins, it won't be valid when you have Composer, Sass and ES6 in your project. Unless you upload all the processed files into Git, which is a terrible idea ;)

This is why we stick to Buddy CI/CD, where we are building dev and prod packages, upload zips into various locations and deploy to SVN. Github actions probably won't be able to do that in a long time :(
