A github action to install k6 on GitHub ubuntu runners
The official Grafana GitHub actions for K6 install and run the k6 binary.
This action installs only, without running, so the workflow can do what it wants with k6, like invoke it via a build script or something.
Also, this only installs for the GitHub Unbuntu runners.
This runner is simply packing the official instructions for Debian/Ubuntu into a composite GitHub action.
