feat: generate the gt command reference from gitea/cli

update_cli_docs.sh runs gt's own generator and lays the pages out for the
site: one directory per command group, front matter, titles, sidebar
order, fenced help text and rewritten links. --released succeeds while no
series is documented. A weekly workflow proposes updates like the runner's.
