fixup! release: create draft GitHub release with packages & installers

The `prereqs` job is needed in this new job, and later on we still need
to list those jobs as needed because even if they are transitively
needed via the `validate-installers` job, the workflow definition
requires them to be able to resolve, say,
`needs.prereqs.outputs.tag_name`.
