Add support to extract release archives

[hegerdes]

Problem:
Many GH Release publish multiple assets. Most of the time these assets are not directly usable because they are packages in an archive. A good example is the prometheus repo where every asset is a tar.gz or zip archive.

To use the executables in the archive users must use or even install additional platform dependent tools to extract these. In GH Action this is a substantial overhad with at least one additional step in each workflow.

Solution:
I would like the option to automatically extract all archives while using this action. This action is based on NodeJS and has the power to extract files without handling platform specific requirements.

The alternative would be to use at least one or more additional steps to setup tar, gzip or a windows alternative for zip to extract files.

I will provide a reference implementation as soon as possible

@robinraju it looks like this was fixed and merged but I don't believe the documentation is currently incorrect since it doesn't exist in release 1.7

Any chance we could get a release with this functionality?
