fix(release): add data/versions/v1.4.yaml

v1.4/ pages use the {{< version-pin >}} shortcode, which reads
data/versions/<version>.yaml and calls errorf on missing files,
halting the build. hack/release_next.sh creates this file during
release, but the upstream cozystack/cozystack tags.yaml workflow's
`git add content hugo.yaml` step omits data/versions/ so it never
gets committed.

Hotfixes the missing snapshot for the v1.4.0 cut. Source of truth
for talos pins: packages/core/talos/images/talos/profiles/installer.yaml
in cozystack/cozystack at v1.4.0 → Talos v1.13.0.
