Here's the design:
- We track changes to github.com/cloudfoundry/bosh-package-golang-release/blob/main/packages/golang-1-linux/version
  which denotes the latest available golang version.
- On change to above, CI fires the task that revendors the package and
  pushes to the repo.
- This updates the package's spec.lock and triggers the usual good olde
  rootfs building...release process.
- The CATS will guard against go update errors.
