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.

+Create or update a variable
+
+## Synopsis
+
+```text
+Create or update a variable.
+
+The value comes from --body, --body-file or standard input when it is not a terminal (one
+trailing line break is removed), or else from a prompt. --env-file sets every NAME=value of a
+dotenv file instead.
+```
+
+```
+gt variable set [<name>] [flags]
+```
+
+## Examples

+```
+# set a repository variable
+$ gt variable set ENVIRONMENT --body staging
+# set an organization variable from a file
+$ gt variable set CONFIG --org acme < config.json
+# set the variables of a dotenv file
+$ gt variable set --env-file .env
+```
