GitHub's official Actions are available in the repositories here: https://github.com/actions
Third party Actions can be found somewhat haphazardly (by browsing repositories and scanning their readmes). Example: https://github.com/docker/build-push-action
To avoid the haphazard nature of browsing, I'd like to use GitHub's search box but limit results to only repositories that are GitHub Actions - is there a way to search GitHub exclusively for repositories that are GitHub Actions? (that is, repos that can be the value provided to the uses instruction in a workflow.yml file)
