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.

+Authenticate gt and git with Gitea
+
+## Synopsis
+
+```text
+Authenticate gt and git with Gitea.
+
+gt keeps the accounts of each instance in hosts.yml and their tokens in the system
+keyring, or in a private file when you choose so. One account per instance is active;
+--user or GITEA_CLI_USER selects another for a single command. GITEA_TOKEN, together with
+GITEA_CLI_HOST or GITEA_INSTANCE_URL, replaces the stored credentials of its instance for the
+active account too; it must belong to the account that --user or GITEA_CLI_USER names. See
+gt help environment for how commands select the instance.
