I'm trying to do a GitHub action that need to upload an artifact
But since I'm already in an action I can't call actions/upload-artifact@v2
There are some answer that suggest downloading the action in mine but this one is in JS and mine in shell.
Also the GitHub API doesn't give any result on how to upload one (only download, list or delete)
Therefore my question is: Is there a way to upload an artifact to GitHub from a shell script?
