Enterprise-managed settings now support autoUpdate for plugin marketplaces

GitHub Enterprise now lets admins enable autoUpdate for plugins sourced from GitHub Marketplace via managed settings.

Previously, rolling out a new plugin version across an enterprise meant either rebuilding every managed repo or asking developers to update manually. The autoUpdate field on an extraKnownMarketplaces block in .github-private/copilot/managed-settings.json now handles it: set it to true, and the plugin updates automatically when a new version is published on the Marketplace — no per-repo config changes needed.

This works with Copilot Business and Copilot Enterprise plans, across the Copilot app, CLI, and VS Code.

Why a builder cares: This kills a major friction point for platform teams running Copilot plugins at scale — no more hunting down stale versions across hundreds of repos.
