Suppress false-positive Spectral lint on WebSocket endpoint (#13842)

The /ws path uses HTTP 101 (Switching Protocols), which is the correct
response for a WebSocket upgrade but not a 2xx. The built-in
operation-success-response rule fires as a false positive because
OpenAPI 3.x has no native WebSocket support.

Add a path-scoped override in .spectral.yaml to disable the rule for
/ws only, leaving it active for all other operations.
