fix(website): build on Hugo 0.147 again (site.Data), chown site trees even when the CI build fails

hugo.Data is not available in the alpine Hugo the deploy job uses; the
failed render left the webroot half-cleaned and root-owned because the
chown only ran after a successful build. It is an EXIT trap now.
