Fix corner case in TestKnnVectorQuery.testRandomWithFilter [LUCENE-10589]

`TestKnnVectorQuery.testRandomWithFilter` can fail with java.lang.UnsupportedOperationException.

Reproducible command

```java
./gradlew test --tests TestKnnVectorQuery.testRandomWithFilter -Dtests.seed=1DA39B92702DAC45 -Dtests.multiplier=3
```

```java
org.apache.lucene.search.TestKnnVectorQuery > testRandomWithFilter FAILED
java.lang.UnsupportedOperationException: exact search is not supported

```

In some edge cases (depending on the random seed), [KnnVectorQuery.java#147](https://github.com/apache/lucene/blob/fe9d26178d033f585c08a5e86708063ac0ec0c9e/lucene/core/src/java/org/apache/lucene/search/KnnVectorQuery.java#L147) becomes false, and then `exactSearch()` is called.

The upper bound of [the test range query (filter)](https://github.com/apache/lucene/blob/fe9d26178d033f585c08a5e86708063ac0ec0c9e/lucene/core/src/test/org/apache/lucene/search/TestKnnVectorQuery.java#L554) could be 200 (the max value of "tag" field + 1) instead of lower + 150 to make it "unrestrictive"?
