The Outline CLI references to the invalid version of Outline SDK

1. Looks like the Outline CLI references to the invalid version of Outline SDK.
   If I run go run github.com/Jigsaw-Code/outline-sdk/x/examples/outline-cli@latest -transport "ss://<outline-server-access-key>" under the root I get the rrorr:
