fix(ci): increase test-examples timeout and reduce sleep in error_handling example (#760)

The `test-examples` CI job running `streaming_mode.py all` consistently
times out at 120 seconds. This happens because the job runs 10
sequential live API examples, and the error_handling example's `sleep
60` bash command (which intentionally triggers an asyncio timeout after
10s) adds unnecessary wall-clock time, especially with slower CLI
versions.

**Changes:**

1. **`examples/streaming_mode.py`**: Reduce the bash sleep duration from
60 seconds to 5 seconds in the timeout/error-handling example. The
internal `asyncio.timeout(10.0)` still fires correctly since 5s < 10s
would let it complete normally, but the important behavior
(demonstrating timeout handling) is preserved. A 5-second sleep is
sufficient to show the pattern without wasting 50+ seconds of CI budget.

2. **`.github/workflows/test.yml`**: Increase the `timeout` for
`streaming_mode.py all` from 120s to 180s to provide headroom for API
latency variance across the full suite of examples.
