Align getStatus not-found message with v3 wording (review item 5)

v3 DurableClient.getStatus throws on the extension's HTTP 404 with 'This usually means we could not find any data associated with the instanceId provided: <id>.'. Mirror that sentence verbatim (only the HTTP-404-specific first sentence is replaced, since the gRPC path has no HTTP 404). Update the not-found tests to assert the v3 message.
