ci: publish Kepler binary on releases

This commit updates the release workflow to publish the Kepler binary
when release is created.
Currently we only publish the binary for Linux-amd64. Once we have
multi-arch support, we can publish the binary for other platforms as
well and update the workflow accordingly.
