This action downloads an asset from a GitHub release and provides some release details as output. Private repos are supported. I modify orginally @dsaltares/fetch-gh-release-asset to work on composite action insteed docker.

When you use self-hosted github runner in docker, shared directory with workspace doesn't work. So this is why i decade to use composite action.

thx dsaltares for orginal bash script!

This action only supports Linux runners as this is a docker container action. If you encounter Error: Container action is only supported on Linux then you are using non-linux runner.
