Remove github-release workflow (#76)

It's currently broken, and needs to align with the set of instructions
outlined in `RELEASING.md` which are currently manual.

At some future date, those instructions should be turned into
something that can successfully handle the release for us, including
opening a PR to `bazelbuild/bazel-central-registry`.
