[SPARK-52183] Update SparkSQLRepl example to show up to 10k rows

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

This PR aims to update `SparkSQLRepl` example to show up to 10k rows.

### Why are the changes needed?

Currently, `SparkSQLRepl` uses the `show()` with the default parameters. Although we cannot handle large-numbers of rows due to `grpc_max_message_size`, we had better have more reasonable default value.

```SQL
spark-sql (default)> SELECT * FROM RANGE(21);
+---+
| id|
+---+
|  0|
|...|
| 19|
+---+
only showing top 20 rows
Time taken: 118 ms
```

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

This is an example.

### How was this patch tested?

Manual test.

```SQL
$ swift run
spark-sql (default)> SELECT * FROM RANGE(10001);
...
only showing top 10000 rows
Time taken: 142 ms
```

### Was this patch authored or co-authored using generative AI tooling?

No.

Closes #159 from dongjoon-hyun/SPARK-52183.
