Setup buf for GitHub Actions

This action will install the bufbuild/buf tooling inside of your GitHub Action workflow, making it available on the $PATH for use in your workflow build steps.

The bufbuild teams also offers a GitHub Actions workflow example using CMake, if that's more to your liking.

Current limitations

The buf tooling is still a work in progress.

As of 2020-06-25, only builds for Linux and Darwin are available. For this reason, this action will fail if used with a Windows or macOS runner.

Usage

Using the action is very simple.
