[MINOR][SQL][DOCS] failOnDataLoss has effect on batch queries so fix the doc

## What changes were proposed in this pull request?

According to the [Kafka integration document](https://spark.apache.org/docs/2.4.0/structured-streaming-kafka-integration.html) `failOnDataLoss` has effect only on streaming queries. While I was implementing the DSv2 Kafka batch sources I've realized it's not true. This feature is covered in [KafkaDontFailOnDataLossSuite](https://github.com/apache/spark/blob/54da3bbfb2c936827897c52ed6e5f0f428b98e9f/external/kafka-0-10-sql/src/test/scala/org/apache/spark/sql/kafka010/KafkaDontFailOnDataLossSuite.scala#L180).

In this PR I've updated the doc to reflect this behavior.

## How was this patch tested?

```
cd docs/
SKIP_API=1 jekyll build
```
Manual webpage check.

Closes apache#24932 from gaborgsomogyi/failOnDataLoss.
