[SPARK-36109][SS][TEST] Check data after adding data to topic in Kafk…

…aSourceStressSuite

### What changes were proposed in this pull request?

This patch proposes to check data after adding data to topic in `KafkaSourceStressSuite`.

### Why are the changes needed?

The test logic in `KafkaSourceStressSuite` is not stable. For example, https://github.com/apache/spark/runs/3049244904.

Once we add data to a topic and then delete the topic before checking data, the expected answer is different to retrieved data from the sink.

### Does this PR introduce _any_ user-facing change?

No

### How was this patch tested?

Existing tests.

Closes apache#33311 from viirya/stream-assert.
