Create a snapshot

POSThttps://api.vercel.com/v3/sandboxes/sessions/{sessionId}/snapshot
Creates a point-in-time snapshot of a running session's filesystem. Snapshots can be used to quickly restore a session to a previous state or to create new sessions with pre-configured environments. The session must be running and able to accept commands for a snapshot to be created. The session will be terminated after the snapshot is created. Unlike v2, snapshots expire after 7 days when neither the request nor the sandbox configuration specifies an expiration.
