[feat req] Keep filename as name when path uses wildcard

[rafaellehmkuhl]

What would you like to be added?

I think it would be good if we can somehow specify that files found with path wildcards can have their name kept on the artifact. Basically the same that is done today if one does not specify the name, but outside the zip.

Why is this needed?

Having all the files inside the zip forces one to download a big zip instead of just the needed file, when the action runs on a matrix (e.g.: generation of packages for multiple OSs).
