[SPARK-53739] Add pi-preview-with-eventlog.yaml example

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

This PR aims to add `pi-preview-with-eventlog.yaml` example.

### Why are the changes needed?

To show how to use `Apache Spark 4.1.0-preview2` properly. Mainly, we have three difference.

1. Hadoop versions are different.
```
- spark.jars.packages: "org.apache.hadoop:hadoop-aws:3.4.1"
+ spark.jars.packages: "org.apache.hadoop:hadoop-aws:3.4.2"
```

2. Spark 4.1.0-preview2 with Hadoop 3.4.2 requires more memory.

```
spark.driver.memory: "2g"
```

3. Docker images are different.

```
- spark.kubernetes.container.image: "apache/spark:4.0.1-java21-scala"
+ spark.kubernetes.container.image: "apache/spark:4.1.0-preview2-java21-scala"
```

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

No behavior change because this is an example.

### How was this patch tested?

Manually because this is an example.

Since `4.1.0-preview2` image is not published yet, I built the image locally and used it.

```
$ ./bin/docker-image-tool.sh -r docker.io/apache -t 4.1.0-preview2-java21-scala build
```

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

No.

Closes #353 from dongjoon-hyun/SPARK-53739.
