Now we can create the casks of some specific release ('latest' in this
case) at will, based purely on the artifact files and on nothing in the
repo. We do not even need to fetch the repo.
This is still some kind of WIP, because we do not have the secrets and
not even a proper homebrew fork in our organization.
THIS WILL NOT WORK out of the box. Refer to PR #1008 to get instruction
on additional steps needed to make this run.
[note]
Remove cask generation from normal release workflow.
Later on the release workflow has to trigger the cask workflow.
