chore(ci): migrate release-drafter categories to when and build OAS from the tag

release-drafter v7 deprecated the top-level `categories[*].label` /
`categories[*].labels` fields; move each into the category's `when`
condition to clear the deprecation warning (removal is planned upstream).

Also generate the OpenAPI schema from the release tag instead of the
`release/x.y.z` branch, so the OAS matches the exact ref the release
docker images are built from (release-x-manual-docker-containers.yml
already checks out the tag).
