Fix stale quickstart integration assertion (#15677)

TL;DR: update the quickstart integration assertion to match the current
example output.

- replace the stale `Status:` expectation for
`01_quickstart_constructor` with `Server:`, `Items:`, and `Text:`
- keep the existing guard against `Server: unknown`
