docs(scloud): Update Serverpod Cloud CLI reference docs

[serverpod-cloud-docs-sync]

Auto-generated update of the Serverpod Cloud CLI reference docs from the
command definitions in serverpod_cloud.

Triggered by: https://github.com/serverpod/serverpod_cloud/commit/54a1968da1a5f06f5531a2ad28465a009a384e76

This branch (auto/cli-docs-sync) is force-updated on every relevant push to
main, so always review the latest diff. Do not push manual commits to it —
they will be overwritten. Curated command intros (_<command>.md) are
maintained directly on main and are preserved by the generator.
