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.

+
+Configure git to use gt for credentials
+
+## Synopsis
+
+```text
+Configure git to ask gt for the credentials of an instance, so that git push and fetch
+over HTTPS use the active account, or the account of --user. gt's own clone and checkout
+commands do not need this.
+
+Other credential helpers, such as a system keychain, are turned off for the instance:
+otherwise they answer first and keep a copy of gt's token. --keep-helpers keeps them.
+```
+
+```
+gt auth setup-git [flags]
+```
+
+## Examples
+
+```
+$ gt auth setup-git
+$ gt auth setup-git --host gitea.com
+# Only for the current repository, always as alice
+$ gt auth setup-git --local --user alice
+```
+
+## Options

+```
+  -h, --help           help for setup-git
