Download workflow artifact GitHub Action

An action that downloads and extracts uploaded artifact associated with given workflow and commit or other criteria.

Let's suppose you have a workflow with a job in it that at the end uploads an artifact using actions/upload-artifact action and you want to download this artifact in another workflow that is run after the first one. Official actions/download-artifact does not allow this. That's why I decided to create this action. By knowing only the workflow name and commit SHA, you can download the previously uploaded artifact from different workflow associated with that commit and use it.

Usage

If commit or pr or branch or run_id or workflow_conclusion is not specified then the artifact from the most recent completed workflow run will be downloaded.

Do not specify pr, commit, branch, run_id together or workflow_conclusion and run_id together. Pick just one of each or none.
