feat(spark): Nebula spark connector does not support spark 3.4+

### Describe the enhancement requested

We should decide what to do with it. At the moment it is a part of Spark CI.

```
Exception in thread "main" java.lang.RuntimeException: Your current spark version 3.4.3 is not supported by the current NebulaGraph Spark Connector.
please visit https://github.com/vesoft-inc/nebula-spark-connector#version-match to know which Connector you need.

### Component(s)

Spark

Inspect the Spark CI setup and the failing Nebula2GraphAr.scala call path, starting with readVertexDF, readAndPutDataIntoWriter, and the SparkValidate.scala:15 failure shown here. Decide how Spark 3.4.3 support should be handled, then rerun the Spark CI example and confirm it no longer fails because the connector rejects that version.
