Explain explicitly what is being packaged with this action

It is not quite clear to me what artifacts are being packaged by this action by default. I see that I can use EXTRA_FILES to request additional files, but I can't see what files are being packaged by default.

Sure I can do a quick experiment and figure it out on my own, but it would be nice and helpful if the documentation spelled it out.

The build.sh in your project outputs a list of files to be packaged up.
